1+Version 0.3.8.0 (2013-10-11)
2+ * Fixed the example code in `FromField`, thanks to Adam Bergmark.
3+
4+ * Added `Notification.getBackendPID`.
5+
6+Version 0.3.7.1 (2013-09-12)
7+ * Relaxed the dependency on bytestring-0.10 back to bytestring-0.9,
8+ courtesy of Michael Snoyman
9+
10+Version 0.3.7.0 (2013-09-11)
11+ * Added `aeson` as a dependency.
12+
13+ * Added ToField and FromField instances for aeson's JSON.Value type,
14+ courtesy of Bas van Dijk.
15+
16+ * Added toJSONField and fromJSONField helper functions for declaring
17+ FromField/ToField JSON instances to other Haskell types, courtesy
18+ of Bas van Dijk.
19+
20+ * Added a FromField instance for (), corresponding to postgresql's void
21+ type.
22+
23+ * Added liftConversion and liftRowParser functions to the Internal
24+ module, for lifting IO actions into the respective monads.
25+
26+ * The SqlError predicates available in the Transaction module are now
27+ also exported from the Errors module.
28+
29+ * Various documentation fixes.
30+
31+Version 0.3.6.0 (2013-08-19)
32+ * Added the json type to BuiltinTypes and TypeInfo.Static, courtesy of
33+ Manuel Gómez.
34+
35+ * Removed the remaining internal dependencies on BuiltinTypes from
36+ FromField. Added the TypeInfo.Macro module as a result.
37+
38+ * Deprecated the BuiltinTypes module, which will be removed several
39+ months from now. Fixed the example code in FromField to reflect
40+ this change.
41+
42+Version 0.3.5.0 (2013-08-09)
43+ * Added an FromRow instance for Vector, semantically identical to the
44+ existing FromRow instance for [], courtesy of Doug Beardsley
45+
46+ * Reworked the documentation for the Copy module, and tweaked the
47+ documentation for the LargeObjects module.
48+
49+Version 0.3.4.0 (2013-07-23)
50+ * Added direct support for COPY IN and COPY OUT, without having
51+ to use raw postgresql-libpq calls and postgresql-simple's Internal
52+ module.
53+
54+ * Changed `getNotification` so that it throws a IOError (resource vanished)
55+ exception instead of an ErrorCall exception when it fails to fetch
56+ the connection's file descriptor from libpq.
57+
58+Version 0.3.3.2 (2013-06-18)
59+ * Optimized the definition of `mconcat` in the Monoid instance for
60+ the Query type, courtesy of Joey Adams.
61+
62+Version 0.3.3.1 (2013-06-06)
63+ * `getNotification` now works on Windows, albeit using a one-second
64+ polling loop, courtesy of Joey Adams.
65+
66+Version 0.3.3.0 (2013-05-29)
67+ * Fixed two issues with the fold operator: fold would raise the wrong
68+ exception, and gave the database cursor a static name preventing
69+ folds from being nested. Thanks to Joey Adams for his
70+ work on these issues.
71+
72+Version 0.3.2.0 (2013-05-20)
73+ * Added a savepoint abstraction to the Transaction module, courtesy
74+ of Joey Adams
75+
76+Version 0.3.1.2 (2013-04-29)
77+ * Fixed hstore parser to not unnecessarily reverse the key-value pairs
78+
79+Version 0.3.1.1 (2013-04-29)
80+ * Fixed hstore parser to recognize empty hstores, courtesy of Simon
81+ Meier
82+
83+Version 0.3.1.0 (2013-04-26)
84+ * Added support for Range and Composite types to the TypeInfo system.
85+
86+ * Added support for hstore types in the Simple.HStore module.
87+
88+ * Improved documentation of the FromField module.
89+
90+Version 0.3.0.1 (2013-03-26)
91+ * A large chunk of the documentation inside the FromField module had
92+ silently failed to render in Haddock.
93+
94+Version 0.3.0.0 (2013-03-25)
95+ * Added support for PostgreSQL's Array Types. Thanks to Jason Dusek
96+ for his work on this feature.
97+
98+ * Added a brand new TypeInfo system that gives FromField instances
99+ convenient and efficient access to the pg_type metatable. This
100+ replaced the older typename cache, and was neccesary to properly
101+ support postgres array types. Thanks to Bas van Dijk for his
102+ work on this feature.
103+
104+ * Changed the type of the `fromField` and `fromRow` methods to allow
105+ a restricted set of IO actions, and stopped pre-calculating the type
106+ name of every column. As a result, the type of the `typename`
107+ operator changed from `Field -> ByteString` to
108+ `Field -> Conversion ByteString`, where Conversion is the new monad
109+ that conversion computations run inside.
110+
111+ * Improved the documentation of the FromField module.
112+
113+ * Added the Database.PostgreSQL.Simple.Errors module, which offers
114+ some predicates and functions for interpreting SqlError values, courtesy
115+ of Leonid Onokhov.
116+
117+ * Added a the name of a column and the associated table's object identifier
118+ to ResultError exceptions, courtesy of Jeff Chu.
119+
120+ * Moved most of the more detailed transaction operators into the
121+ Database.PostgreSQL.Simple.Transaction module.
122+
123+ * Changed withTransactionModeRetry to accept a predicate of which
124+ SqlErrors to retry, due to the fact that serialization errors can
125+ sometimes manifest themselves as constraint violations. Thanks
126+ to Oliver Charles for pointing this out and implementing the change.
127+
128+ * Added simple tests of the fold operator, thanks to Joey Adams.
129+
130+ * Added simple tests of the array conversion code.
131+
132+ * Added recognition of -- comments in the quasiquoter, which are
133+ now stripped out.
134+
135+
136+Version 0.2.4.1 (2012-08-29)
137+ * Fixed the documentation of `In`. Thanks to rekado and dstcruz for
138+ pointing this out.
139+
140+Version 0.2.4.0 (2012-08-23)
141+ * Added the `withTransactionSerializable` and `withTransactionModeRetry`
142+ operators, thanks to Joey Adams.
143+
144+Version 0.2.3.0 (2012-08-09)
145+ * Added the `returning` operator, thanks to Jason Dusek
146+
147+Version 0.2.2.0 (2012-07-26)
148+ * Added a ToRow instance for the (:.) type, courtesy of Leonid Onokhov
149+
150+ * Added the type oid for PostgreSQL's `uuid` type to BuiltinTypes
151+
152+Version 0.2.1.0 (2012-07-23)
153+ * Added the FromRow.fieldWith operator, thanks to Leonid Onokhov
154+
155+ * Added a type synonym for FieldParser
156+
157+Version 0.2.0.1 (2012-06-21)
158+ * Fixed a compatibility problem with PostgreSQL 8.1, which does not allow
159+ clients to set their own value for `standard_conforming_strings`. This
160+ connection variable is still set to `on` for PostgreSQL 8.2 and later.
161+
162+Version 0.2: (2012-06-19)
163+ * Removed the conversion from `timestamp` to `UTCTime`. Some code will be
164+ broken even though it will still compile.
165+
166+ * Renamed a number of data constructors, mostly in the BuiltinTypes module.
167+
168+ * Exported ToRow/FromRow from Database.PostgreSQL.Simple
169+
170+
171+Version 0.1.4.3: (2012-06-10)
172+ * Fix language extensions for compatibility with GHC 7.0
173+
174+Version 0.1.4.2: (2012-06-10)
175+ * Fix a wayward dependency on Text.
176+
177+Version 0.1.4.1: (2012-06-10)
178+ * Added support for timezones with minutes in their UTC offset.
179+
180+Version 0.1.4: (2012-06-10)
181+ * Removed pcre-light dependency, courtesy of Joey Adams.
182+
183+ * Reworked support for the Time types.
184+
185+ * The conversion from PostgreSQL's `timestamp` (without time zone) type
186+ to Haskell's `UTCTime` type is deprecated and will be removed in 0.2.
187+
188+ * `Data.Time.LocalTime` now has `FromField`/`ToField` instances. It is
189+ now the preferred way of dealing with `timestamp` (without time zone).
190+
191+ * `Database.PostgreSQL.Simple.Time` is a new module that offers types
192+ that accomodate PostgreSQL's infinities.
193+
194+ * All time-related `FromField`/`ToField` instances are now based on new,
195+ higher-speed parsers and printers instead of those provided by the
196+ time package included in GHC.
197+
198+ * Planned breaking changes for 0.2:
199+
200+ * Removing the conversion from `timestamp` to `UTCTime`.
201+
202+ * Renaming some of the type names in `BuiltinTypes`.
203+
204+
205+Version 0.1.3: (2012-05-30)
206+ * Made ZonedTime an instance of FromField and ToField
207+
208+ * Added getNotificationNonBlocking
209+
210+
211+Version 0.1.2: (2012-05-09)
212+ * Switched to libpq-based escaping for bytea types; Binary now works with
213+ PostgreSQL 8 courtesy of Joey Adams.
214+
215+ * postgresql-simple now sets standard_conforming_strings to "on". This
216+ per-connection variable is initialized according to the server
217+ configuration, which defaults to "off" for PostgreSQL < 9, and "on"
218+ for PostgreSQL >= 9. You may need to adjust any string literals in
219+ your SQL queries, or set the variable yourself.
220+
221+ * Exported (:.) from Database.PostgreSQL.Simple
222+
223+
224+Version 0.1.1: (2012-05-06)
225+ * Added some preliminary documentation for the Ok, Notification, and
226+ LargeObjects modules
227+
228+ * Implemented the `fail` method for the monad instance for `Ok`.
229+
230+ * Fixed a bug relating to handling the transaction level
231+
232+
233+Version 0.1: (2012-05-04)
234+ * Renamed several modules, typeclasses, and functions:
235+
236+ QueryParams (renderParams) -> ToRow (toRow)
237+ QueryResults (convertResults) -> FromRow (fromRow)
238+ Param (render) -> ToField (toField)
239+ Result (convert) -> FromField (fromField)
240+
241+ * Added the `Database.PostgreSQL.Simple.Ok` module, a variation of
242+ `Either SomeException` that has an instance for `Alternative` and also
243+ uses a list of exceptions to track the ways it has failed.
244+
245+ * Changed the return type of `fromField` and `fromRow` from
246+ `Either SomeException` to `Ok`.
247+
248+ * Thanks to suggestions from Ozgun Ataman, the `FromRow` typeclass has been
249+ massively improved. The result is simpler definitions and better
250+ compositionality. Also, user-defined instances need not be to be
251+ concerned about forcing the converted results to WHNF. Here is an
252+ example comparing the old to the new:
253+
254+ instance (Result a, Result b) => QueryResults (a,b) where
255+ convertResults [fa,fb] [va,vb] = do
256+ !a <- convert fa va
257+ !b <- convert fb vb
258+ return (a,b)
259+ convertResults fs vs = convertError fs vs 2
260+
261+ instance (FromField a, FromField b) => FromRow (a,b) where
262+ fromRow = (,) <$> field <*> field
263+
264+ * Added `(:.)`, a pair that allows one to compose `FromRow` instances:
265+
266+ instance (FromRow a, FromRow b) => FromRow (a :. b) where
267+ fromRow = (:.) <$> fromRow <*> fromRow
268+
269+ * Moved the contents `Field` module into the `FromField` module.
270+
271+ * Removed the `RawResult` type.
272+
273+ * Added `DefaultIsolationLevel` as a distinct `IsolationLevel` option
274+ and `DefaultReadWriteMode` as a distinct `ReadWriteMode`.

77−
78− * *Breaking change*: Use `Only` package's `Only` for a common 1-tuple.
79−
80− Consider a downstream library depending already both on
81− `Only` and `postgresql-simple` package. This library my define
82− a `MyClass` with instances for `Only.Only` and `PostgreSQL.Only`.
83− As now these types are the same, a library would break.
84− Therefore I consider "merging" types a breaking change.
85−
86− There are two ways for adopting this change in that scenario:
87−
88− - Either CPP-guard `PostgreSQL.Only` instance with
89−
90− ```haskell
91− #if !MIN_VERSION_postgresql_simple(0,6,0)
92− instance MyClass (PostgreSQL.Only a) where ...
93− #endif
94− ```
95−
96− - or simply remove it and add `postgresql-simple >=0.6` lower bound,
97− making sure that there's only single `Only`.

164− goes to Edgar Gomes and Silk for finding and fixing this mistake.
165−
166− * Modified `withTransaction` and friends to ignore `IOError`s when
167− attempting to roll back the transaction. This fixes a buggy

189− * Added a truncated changelog to the source distribution.
190−
191−### Version 0.5.1.3 (2016-04-30)
192− * Implemented the Monad of No Return proposal, future-proofing
193− postgresql-simple against future releases of GHC.
194−
195− * Fixed a rare and usually benign race condition where
196− `getNotification` could end up waiting on a newly reallocated
197− file descriptor index, potentially leading to deadlock if the
198− descriptor does not become readable promptly. This fix only
199− applies to GHC 7.8 or later, as it depends on `threadWaitReadSTM`.
200−
201− * Tweaked the time parsers to accept times of day of the form `hh:mm`,
202− omitting seconds, following changes made to aeson.
203−
204− * Updated the documentation of the `In` type to point out a gotcha
205− when using the SQL fragment `... NOT IN ?` with `In []`. Thanks
206− goes to Simon Michael and Dan Haraj for bringing this issue to
207− my attention.
208−
209−### Version 0.5.1.2 (2015-12-14)
210− * The syntax generated for empty arrays was changed so that
211− postgresql's type inference would work better, thanks to
212− Amit Levy.
213−
214− * Further revision and expansion of the new Time documentation.
215−
216−### Version 0.5.1.1 (2015-12-02)
217− * This is a documentation-only release
218−
219− * The documentation of the `Time` module has been completely
220− rewritten, and is far longer and more informative. It contains
221− a brief overview of civil time, the semantics of postgresql's
222− time types, and their relation to Haskell's time types via
223− postgresql-simple.
224−
225− * The documentation of `connectPostgreSQL` has been modified to
226− mention the effects of environment variables on the connection
227− string parameters.
228−
229− * The documentation of `HStore.Internal` has been unhidden from
230− haddock.

234−### Version 0.5.1.0 (2015-10-22)
235− * Optimized the implementation of the streaming operators to avoid
236− creating intermediate lists of rows, thanks to Timo von Holtz.
237−
238− * Added default instances for `ToRow` and `FromRow` that depend on
239− Generics, thanks to Alexey Khudyakov.
240−
241− * Fixed support for bytestring-0.9 and GHC 7.4.
242−
243−### Version 0.5.0.1 (2015-09-21)
244− * Fixed a bug when printing a `ZonedTime` with a negative offset
245− that is not a whole number of hours.
246−
247−### Version 0.5.0.0 (2015-09-19)
248− * Removed the deprecated `BuiltinTypes` module.
249−
250− * Modified the SQL quasiquoter so that it returns a `Query`, not
251− an overloaded string, and so that the `OverloadedStrings` language
252− extension is no longer necessary, thanks to Mike Ledger.
253−
254− * Moved away from `blaze-builder` in favor of `bytestring-builder`. This
255− shouldn't affect very many people, but does reduce the transitive
256− dependencies.
257−
258− * Rewrote the timestamp printers to use the new `Prim`
259− infrastructure in `bytestring-builder`. The new printers should
260− be a fair bit faster.
261−
262− * Added support for exclusion violations to the `ConstraintViolation`
263− type in the Errors module, thanks to João Cristóvão.
264−
265− * Moved away from the `uuid` package in favor of the `uuid-types` package,
266− thanks to Bardur Arantsson. This shouldn't affect anybody, but does
267− reduce the transitive dependencies.
268−
269− * Postgresql-simple now explicitly assumes the UTF8 character encoding
270− for communication between the client and server. All database encodings
271− support UTF8 except for Mule Internal Code, the Multilingual
272− Extensions for Emacs. An exception should be raised upon
273− connecting to a database by the backend if the backend cannot
274− accommodate this requirement.
275−
276− * Added `Eq` and `Typeable` instances for `Connection`.
277−
278− * Added the `foldWith`, `forEachWith`, and `returningWith` families
279− of functions courtesy of Travis Staton.
280−
281− * Support for Ranged types, with thanks to Leonid Onokhov for his
282− contributions.
283−
284− * The `FromField` instance for JSON now allows for top-level values that
285− are not objects or arrays, thanks to Sam Rijs.
286−
287− * The timestamp parsers have been replaced with those now in Aeson.
288− Janne Hellsten adapted the old parsers from postgresql-simple for
289− inclusion in Aeson; Bryan O'Sullivan rewrote those parsers to be
290− faster, with some tweaks contributed by myself. And now to
291− bring the effort full circle, the result has been brought back to
292− postgresql-simple, with some adaptations.
293−
294− * Fixed a bug in the typeinfo system where postgresql's `_record` type
295− was being reported as a basic type and not an array type. Thanks to
296− Nickolay Kolev for helping to expose this issue.
297−
298− * Fixed a bug with the `typeInfo` operator, thanks to Timmy Tofu. In the
299− case of parsing subfields of arrays and composites, it would fetch the
300− `TypeInfo` of the array or composite type and not the subtype.
301−
302−### Version 0.4.10.0 (2015-02-26)
303− * Added a blurb about SSL/TLS in the documentation for connectPostgreSQL
304−
305− * Moved some functions into the Internal module, courtesy of Aleksey
306− Uimanov.
307−
308−### Version 0.4.9.0 (2014-12-27)
309− * Made the fromField method for PGArray available as pgArrayFieldParser,
310− outside of the typeclass courtesy of Tom Ellis.
311−
312− * Fixed a missing OverloadedStrings pragma in the documentation of SqlQQ.

314− * Fixed deprecation warnings, courtesy of Simon Hengel.
315−
316−### Version 0.4.8.0 (2014-11-24)
317− * Added support for postgresql's citext type extension via the
318− case-insensitive package.
319−
320− * Added the function parseHStoreList to the HStore module.
321−
322−### Version 0.4.7.0 (2014-10-27)
323− * Added support for very old timestamps to UTCTime. Depending on time
324− zone, very old timestamps can be returned with a offset from UTC that
325− contains seconds.
326−
327− All timezones in the TZ database moved to a time standard offset an
328− integer number of minutes from UTC before 1973, almost all locations
329− moved before 1938, and a solid majority moved before 1921.
330−
331− ZonedTime assumes offsets are a whole number of minutes, and thus the
332− conversion to ZonedTime does not support these timestamps and will
333− still throw a conversion error.
334−
335− Note that PostgreSQL's "timestamp with time zone" (or "timestamptz")
336− type is nearly universally misunderstood. For an explanation, see:
337−
338− https://github.com/lpsmith/postgresql-simple/issues/69

340− Thanks to Michael Snoyman for his assistance with this issue.
341−
342−### Version 0.4.6.0 (2014-10-07)
343− * Added an instance ToField NominalDiffTime.
344−
345−### Version 0.4.5.0 (2014-09-26)
346− * Added support for retrieving NaN and ±Infinity floating point values
347− from postgres to the FromField instances for Float, Double, and Rational.
348− The instance for Scientific is unchanged due to the fact it has no
349− way of representing these special values. Thanks goes to Tom Nielsen
350− for reporting the issue.
351−
352−### Version 0.4.4.1 (2014-09-07)
353− * Fixed a rather serious bug that prevented the COPY module from working
354− at all on unix clients since version 0.4.3.0. Thanks goes to
355− Dmitry Dzhus for reporting the issue.
356−
357− * Added a regression test for the COPY module to the test suite.
358−
359−### Version 0.4.4.0 (2014-08-26)
360− * Added the jsonb type debuting in PostgreSQL 9.4 to the TypeInfo.Static
361− and Builtin tables, and extended the out-of-box json instances to
362− be compatible with the new type. Thanks to Tobias Florek for the
363− patch.
364−
365− * Ported some expanded documentation from mysql-simple, and fixed
366− a documentation typo.
367−
368−### Version 0.4.3.0 (2014-07-10)
369− * connect and exec now use libpq asynchronously on non-Windows platforms.
370− This means we are using threadWaitRead and threadWaitWrite to
371− have GHC's IO manager schedule non-blocking C calls to libpq,
372− instead of using blocking C calls and having the OS kernel do the
373− scheduling. Among other things, this now means that System.Timeout
374− will work with connect and exec on unix platforms.
375−
376− * connect and exec now throw IOErrors instead of SQLErrors in
377− some cases. The intention is for SQLErrors to represent
378− an error returned by the server, and to use IOErrors for errors
379− that originate from client-side code. However, this goal
380− isn't perfectly achieved as of yet.
381−
382−### Version 0.4.2.3 (2014-06-04)
383− * This is strictly a documentation release, with no code changes.
384−
385− * Fixed several documentation typos, thanks to Chris Allen and remdezx.
386−
387− * Expanded the documentation of connectPostgreSQL, including a short
388− overview of common use cases and two new links to the official Postgres
389− documentation about the authentication process.
390−

392−
393−### Version 0.4.2.2 (2014-05-15)
394− * Fixed compatibility with scientific-0.3.\*, thanks to Adam Bergmark
395−
396− * Improved documentation of the FromField module, as well as the fold,
397− foldWithOptions, executeMany, and returning operators.
398−
399−### Version 0.4.2.1 (2014-03-27)
400− * Fixed bug in Values syntax generation
401−
402− * Improved documentation, including examples of multi-row update,
403− a better example for Values, documenting the inaccuracies in reading
404− floating point numbers from the database, and the IsString instance
405− for QualifiedIdentifier.
406−
407−### Version 0.4.2.0 (2014-03-22)
408− * Added ToField and FromField instances for the scientific package
409−
410− * Changed the Identifier and QualifiedIdentifier to use Text in
411− order to avoid encoding errors. Technically this requires a
412− major version bump, but let's pretend 0.4.1.0 didn't happen.
413−
414− * Removed non-exhaustive cases in the ToField instance for Values,
415− and tweaked error messages.
416−
417−### Version 0.4.1.0 (2014-03-22)
418− * Fixed the parsing of arrays containing null values, courtesy of
419− Francesco Mazzoli
420−
421− * Added support for properly escaped identifiers, courtesy of
422− Tobias Florek. See the new Identifier and QualifiedIdentifier
423− types inside Database.PostgreSQL.Simple.Types.
424−
425− * Added support for parameterized VALUES expressions. This is
426− more general than executeMany and returning. See the
427− Database.PostgreSQL.Simple.Types.Values data type.
428−
429−### Version 0.4.0.2 (2014-01-12)
430− * Tweaked C preprocessor directive to be more portable

437− * Update the documentation of `fromField`
438−
439−### Version 0.4.0.0 (2013-12-21)
440− * Changed the calling code of `fromField` so that it always sends
441− a copy of the raw data. This should be a small but significant
442− performance bump for most people most of the time; however it
443− may slow down retrieval of large values not converted directly
444− to ByteString, such as large json, hstore, and array values.
445− See commit 8635f8 for more information.
446−
447− * Added the PGArray type. Thanks to Joey Adams for the suggestion
448−
449− * Fixed JSON decoding, which was almost entirely broken up until now,
450− due to bugs in the version of aeson currently available on Hackage.
451− Thanks to Amit Levy for the report.
452−
453− * Added FromField instances for IORef, MVar, and IOVector.
454−

464− * Added FromField and ToField instances for the `uuid` package,
465− courtesy of Bas van Dijk.
466−

471− unwrapper functions, courtesy of Bas van Dijk.
472−
473−### Version 0.3.8.0 (2013-10-11)
474− * Fixed the example code in `FromField`, thanks to Adam Bergmark.

490− of Bas van Dijk.
491−
492− * Added a FromField instance for (), corresponding to postgresql's void
493− type.
494−
495− * Added liftConversion and liftRowParser functions to the Internal
496− module, for lifting IO actions into the respective monads.
497−
498− * The SqlError predicates available in the Transaction module are now
499− also exported from the Errors module.
500−
501− * Various documentation fixes.
502−
503−### Version 0.3.6.0 (2013-08-19)
504− * Added the json type to BuiltinTypes and TypeInfo.Static, courtesy of
505− Manuel Gómez.
506−
507− * Removed the remaining internal dependencies on BuiltinTypes from
508− FromField. Added the TypeInfo.Macro module as a result.
509−
510− * Deprecated the BuiltinTypes module, which will be removed several
511− months from now. Fixed the example code in FromField to reflect
512− this change.
513−
514−### Version 0.3.5.0 (2013-08-09)
515− * Added an FromRow instance for Vector, semantically identical to the
516− existing FromRow instance for [], courtesy of Doug Beardsley
517−
518− * Reworked the documentation for the Copy module, and tweaked the
519− documentation for the LargeObjects module.
520−
521−### Version 0.3.4.0 (2013-07-23)
522− * Added direct support for COPY IN and COPY OUT, without having
523− to use raw postgresql-libpq calls and postgresql-simple's Internal
524− module.
525−
526− * Changed `getNotification` so that it throws a IOError (resource vanished)
527− exception instead of an ErrorCall exception when it fails to fetch
528− the connection's file descriptor from libpq.
529−
530−### Version 0.3.3.2 (2013-06-18)
531− * Optimized the definition of `mconcat` in the Monoid instance for
532− the Query type, courtesy of Joey Adams.
533−
534−### Version 0.3.3.1 (2013-06-06)
535− * `getNotification` now works on Windows, albeit using a one-second
536− polling loop, courtesy of Joey Adams.
537−
538−### Version 0.3.3.0 (2013-05-29)
539− * Fixed two issues with the fold operator: fold would raise the wrong
540− exception, and gave the database cursor a static name preventing
541− folds from being nested. Thanks to Joey Adams for his
542− work on these issues.
543−
544−### Version 0.3.2.0 (2013-05-20)
545− * Added a savepoint abstraction to the Transaction module, courtesy
546− of Joey Adams
547−
548−### Version 0.3.1.2 (2013-04-29)

550−
551−### Version 0.3.1.1 (2013-04-29)
552− * Fixed hstore parser to recognize empty hstores, courtesy of Simon

555−### Version 0.3.1.0 (2013-04-26)
556− * Added support for Range and Composite types to the TypeInfo system.
557−
558− * Added support for hstore types in the Simple.HStore module.
559−
560− * Improved documentation of the FromField module.
561−
562−### Version 0.3.0.1 (2013-03-26)
563− * A large chunk of the documentation inside the FromField module had
564− silently failed to render in Haddock.
565−
566−### Version 0.3.0.0 (2013-03-25)
567− * Added support for PostgreSQL's Array Types. Thanks to Jason Dusek
568− for his work on this feature.
569−
570− * Added a brand new TypeInfo system that gives FromField instances
571− convenient and efficient access to the pg_type metatable. This
572− replaced the older typename cache, and was necessary to properly
573− support postgres array types. Thanks to Bas van Dijk for his
574− work on this feature.
575−
576− * Changed the type of the `fromField` and `fromRow` methods to allow
577− a restricted set of IO actions, and stopped pre-calculating the type
578− name of every column. As a result, the type of the `typename`
579− operator changed from `Field -> ByteString` to
580− `Field -> Conversion ByteString`, where Conversion is the new monad
581− that conversion computations run inside.
582−
583− * Improved the documentation of the FromField module.
584−
585− * Added the Database.PostgreSQL.Simple.Errors module, which offers
586− some predicates and functions for interpreting SqlError values, courtesy
587− of Leonid Onokhov.
588−
589− * Added a the name of a column and the associated table's object identifier
590− to ResultError exceptions, courtesy of Jeff Chu.
591−
592− * Moved most of the more detailed transaction operators into the
593− Database.PostgreSQL.Simple.Transaction module.
594−
595− * Changed withTransactionModeRetry to accept a predicate of which
596− SqlErrors to retry, due to the fact that serialization errors can
597− sometimes manifest themselves as constraint violations. Thanks
598− to Oliver Charles for pointing this out and implementing the change.
599−
600− * Added simple tests of the fold operator, thanks to Joey Adams.
601−
602− * Added simple tests of the array conversion code.
603−
604− * Added recognition of -- comments in the quasiquoter, which are
605− now stripped out.
606−
607−
608−### Version 0.2.4.1 (2012-08-29)
609− * Fixed the documentation of `In`. Thanks to rekado and dstcruz for
610− pointing this out.
611−
612−### Version 0.2.4.0 (2012-08-23)
613− * Added the `withTransactionSerializable` and `withTransactionModeRetry`
614− operators, thanks to Joey Adams.
615−
616−### Version 0.2.3.0 (2012-08-09)
617− * Added the `returning` operator, thanks to Jason Dusek
618−
619−### Version 0.2.2.0 (2012-07-26)
620− * Added a ToRow instance for the (:.) type, courtesy of Leonid Onokhov
621−
622− * Added the type oid for PostgreSQL's `uuid` type to BuiltinTypes
623−
624−### Version 0.2.1.0 (2012-07-23)
625− * Added the FromRow.fieldWith operator, thanks to Leonid Onokhov
626−
627− * Added a type synonym for FieldParser
628−
629−### Version 0.2.0.1 (2012-06-21)
630− * Fixed a compatibility problem with PostgreSQL 8.1, which does not allow
631− clients to set their own value for `standard_conforming_strings`. This
632− connection variable is still set to `on` for PostgreSQL 8.2 and later.
633−
634−### Version 0.2: (2012-06-19)
635− * Removed the conversion from `timestamp` to `UTCTime`. Some code will be
636− broken even though it will still compile.
637−
638− * Renamed a number of data constructors, mostly in the BuiltinTypes module.
639−
640− * Exported ToRow/FromRow from Database.PostgreSQL.Simple
641−
642−
643−### Version 0.1.4.3: (2012-06-10)
644− * Fix language extensions for compatibility with GHC 7.0
645−
646−### Version 0.1.4.2: (2012-06-10)
647− * Fix a wayward dependency on Text.
648−
649−### Version 0.1.4.1: (2012-06-10)
650− * Added support for timezones with minutes in their UTC offset.
651−
652−### Version 0.1.4: (2012-06-10)
653− * Removed pcre-light dependency, courtesy of Joey Adams.
654−
655− * Reworked support for the Time types.
656−
657− * The conversion from PostgreSQL's `timestamp` (without time zone) type
658− to Haskell's `UTCTime` type is deprecated and will be removed in 0.2.
659−
660− * `Data.Time.LocalTime` now has `FromField`/`ToField` instances. It is
661− now the preferred way of dealing with `timestamp` (without time zone).
662−
663− * `Database.PostgreSQL.Simple.Time` is a new module that offers types
664− that accommodate PostgreSQL's infinities.
665−
666− * All time-related `FromField`/`ToField` instances are now based on new,
667− higher-speed parsers and printers instead of those provided by the
668− time package included in GHC.
669−
670− * Planned breaking changes for 0.2:
671−
672− * Removing the conversion from `timestamp` to `UTCTime`.
673−
674− * Renaming some of the type names in `BuiltinTypes`.
675−
676−
677−### Version 0.1.3: (2012-05-30)
678− * Made ZonedTime an instance of FromField and ToField
679−
680− * Added getNotificationNonBlocking
681−
682−
683−### Version 0.1.2: (2012-05-09)
684− * Switched to libpq-based escaping for bytea types; Binary now works with
685− PostgreSQL 8 courtesy of Joey Adams.
686−
687− * postgresql-simple now sets standard_conforming_strings to "on". This
688− per-connection variable is initialized according to the server
689− configuration, which defaults to "off" for PostgreSQL < 9, and "on"
690− for PostgreSQL >= 9. You may need to adjust any string literals in
691− your SQL queries, or set the variable yourself.
692−
693− * Exported (:.) from Database.PostgreSQL.Simple
694−
695−
696−### Version 0.1.1: (2012-05-06)
697− * Added some preliminary documentation for the Ok, Notification, and
698− LargeObjects modules
699−
700− * Implemented the `fail` method for the monad instance for `Ok`.
701−
702− * Fixed a bug relating to handling the transaction level
703−
704−
705−### Version 0.1: (2012-05-04)
706− * Renamed several modules, typeclasses, and functions:
707−
708− QueryParams (renderParams) -> ToRow (toRow)
709− QueryResults (convertResults) -> FromRow (fromRow)
710− Param (render) -> ToField (toField)
711− Result (convert) -> FromField (fromField)
712−
713− * Added the `Database.PostgreSQL.Simple.Ok` module, a variation of
714− `Either SomeException` that has an instance for `Alternative` and also
715− uses a list of exceptions to track the ways it has failed.
716−
717− * Changed the return type of `fromField` and `fromRow` from
718− `Either SomeException` to `Ok`.
719−
720− * Thanks to suggestions from Ozgun Ataman, the `FromRow` typeclass has been
721− massively improved. The result is simpler definitions and better
722− compositionality. Also, user-defined instances need not be to be
723− concerned about forcing the converted results to WHNF. Here is an
724− example comparing the old to the new:
725−
726− instance (Result a, Result b) => QueryResults (a,b) where
727− convertResults [fa,fb] [va,vb] = do
728− !a <- convert fa va
729− !b <- convert fb vb
730− return (a,b)
731− convertResults fs vs = convertError fs vs 2
732−
733− instance (FromField a, FromField b) => FromRow (a,b) where
734− fromRow = (,) <$> field <*> field
735−
736− * Added `(:.)`, a pair that allows one to compose `FromRow` instances:
737−
738− instance (FromRow a, FromRow b) => FromRow (a :. b) where
739− fromRow = (:.) <$> fromRow <*> fromRow
740−
741− * Moved the contents `Field` module into the `FromField` module.
742−
743− * Removed the `RawResult` type.
744−
745− * Added `DefaultIsolationLevel` as a distinct `IsolationLevel` option
746− and `DefaultReadWriteMode` as a distinct `ReadWriteMode`.

27−Note that the 'Float' and 'Double' instances use attoparsec's 'double'
28−conversion routine, which sacrifices some accuracy for speed. If you
29−need accuracy, consider first converting data to a 'Scientific' or 'Rational'
30−type, and then converting to a floating-point type. If you are defining
31−your own 'Database.PostgreSQL.Simple.FromRow.FromRow' instances, this can be
32−achieved simply by
33−@'fromRational' '<$>' 'Database.PostgreSQL.Simple.FromRow.field'@, although
34−this idiom is additionally compatible with PostgreSQL's @int8@ and @numeric@
35−types. If this is unacceptable, you may find
36−'Database.PostgreSQL.Simple.FromRow.fieldWith' useful.
37−
38−Also note that while converting to a 'Double' through the 'Scientific' type
39−is likely somewhat faster than converting through the 'Rational' type,
40−the 'Scientific' type has no way to represent @NaN@ and @±Infinity@ values.
41−Thus, if you need precision conversion of regular floating point values
42−and the possibility of receiving these special values from the backend,
43−stick with 'Rational'.

199−--
200−-- > host='db.somedomain.com' port=5432 ...
201−--
202−-- This attempts to connect to @db.somedomain.com:5432@. Omitting the port
203−-- will normally default to 5432.
204−--
205−-- On systems that provide unix domain sockets, omitting the host parameter
206−-- will cause libpq to attempt to connect via unix domain sockets.
207−-- The default filesystem path to the socket is constructed from the
208−-- port number and the @DEFAULT_PGSOCKET_DIR@ constant defined in the
209−-- @pg_config_manual.h@ header file. Connecting via unix sockets tends
210−-- to use the @peer@ authentication method, which is very secure and
211−-- does not require a password.
212−--
213−-- On Windows and other systems without unix domain sockets, omitting
214−-- the host will default to @localhost@.
215−--
216−-- > ... dbname='postgres' user='postgres' password='secret \' \\ pw'
217−--
218−-- This attempts to connect to a database named @postgres@ with
219−-- user @postgres@ and password @secret \' \\ pw@. Backslash
220−-- characters will have to be double-quoted in literal Haskell strings,
221−-- of course. Omitting @dbname@ and @user@ will both default to the
222−-- system username that the client process is running as.
223−--
224−-- Omitting @password@ will default to an appropriate password found
225−-- in the @pgpass@ file, or no password at all if a matching line is
226−-- not found. The path of the @pgpass@ file may be specified by setting
227−-- the @PGPASSFILE@ environment variable. See

230−--
231−-- As all parameters are optional and the defaults are sensible, the
232−-- empty connection string can be useful for development and
233−-- exploratory use, assuming your system is set up appropriately.
234−--
235−-- On Unix, such a setup would typically consist of a local
236−-- postgresql server listening on port 5432, as well as a system user,
237−-- database user, and database sharing a common name, with permissions
238−-- granted to the user on the database.
239−--
240−-- On Windows, in addition you will either need @pg_hba.conf@
241−-- to specify the use of the @trust@ authentication method for
242−-- the connection, which may not be appropriate for multiuser

247−-- for more information regarding the authentication process.
248−--
249−-- SSL/TLS will typically "just work" if your postgresql server supports or
250−-- requires it. However, note that libpq is trivially vulnerable to a MITM
251−-- attack without setting additional SSL connection parameters. In

253−-- @verify-full@ in order to perform certificate validation. When @sslmode@
254−-- is @require@, then you will also need to specify a @sslrootcert@ file,

28−types are ambiguous by themselves, and require context to disambiguate.
29−
30−While this behavior may be superficially counterintuitive because the
31−names might suggest otherwise, this behavior is correct. In fact,
32−the \"timezone\" language in both the postgresql and haskell types would
33−be better read as \"offset (from UTC)\", thus we have postgresql's
34−\"timestamp with offset\" corresponding to Haskell's \"time with the
35−offset \'zero\'\" and Haskell's \"time with an offset (that might be
36−nonzero)\". Similarly, postgresql's \"timestamp without an offset\"
37−corresponds to Haskell's \"local time (without an offset)\".
38−
39−It's important to distinguish between an offset, a standard time, and
40−a time zone. An offset is simply a difference of a local time from UTC,
41−such as @+00@, @-05@, or @+05:30@. A standard time specifies an offset
42−(which may vary throughout the year, due to daylight savings) that a
43−region follows, such as Universal Coordinated Time (UTC), Eastern Standard
44−Time\/Eastern Daylight Time (EST\/EDT), or India Standard Time (IST).
45−And a time zone, much like a standard time, is a function from
46−timestamps to offsets.
47−
48−A time zone is different from a standard time because different regions
49−inside a standard time can be governed by different civil authorities with
50−different laws and thus have different histories of civil time. An IANA
51−time zone is any region of the world that has had the same history of
52−civil time since @1970-01-01 00:00+00@.
53−
54−For example, as of today, both @America\/New_York@ and
55−@America\/Indiana\/Indianapolis@ are on the EST\/EDT time standard, but
56−Indiana used to be on Central Standard Time until 1942, and did not observe
57−daylight savings time (EST only) until 2006. Thus, the choice between
58−these two time zones still matters if you are dealing with timestamps
59−prior to 2006, and could become relevant again if (most of) Indiana
60−moves back to Central Time. (Of course, if the Central to Eastern switch
61−was the only difference, then these two time zones would be the same in
62−IANA's eyes, due to their cutoff date of 1970-01-01.)
63−
64−Getting back to practicalities, PostgreSQL's @timestamptz@ type does not
65−actually store an offset; rather, it uses the offset provided to calculate
66−UTC, and stores the timestamp as UTC. If an offset is not provided, the
67−given timestamp is assumed to be a local time for whatever the @timezone@
68−variable is set to, and the IANA TZ database is consulted to calculate an
69−offset from UTC for the time in question.
70−
71−Note that while most (local timestamp, time zone) pairs correspond to exactly
72−one UTC timestamp, some correspond to two UTC timestamps, while others
73−correspond to none at all. The ambiguous case occurs when the civil time
74−is rolled back, making a calendar day longer than 24 hours. In this case,
75−PostgreSQL silently chooses the second, later possibility. The inconsistent
76−case occurs when the civil time is moved forward, making a calendar day less
77−than 24 hours. In this case, PostgreSQL silently assumes the local time
78−was read off a clock that had not been moved forward at the prescribed time,
79−and moves the clock forward for you. Thus, converting from local time
80−to UTC need not be monotonic, if these inconsistent cases are allowed.
81−
82−When retrieving a @timestamptz@, the backend looks at the @time zone@
83−connection variable and then consults the IANA TZ database to calculate
84−an offset for the timestamp in the given time zone.
85−
86−Note that while some of the information contained in the IANA TZ database
87−is a bit of a standardized fiction, the conversion from UTC time to a
88−(local time, offset) pair in a particular time zone is always unambiguous,
89−and the result can always be unambiguously converted back to UTC. Thus,
90−postgresql-simple can interpret such a result as a 'Data.Time.ZonedTime',
91−or use the offset to convert back to 'Data.Time.UTCTime'.
92−
93−By contrast, the @timestamp@ type ignores any offsets provided to it,
94−and never sends back an offset. Thus, postgresql-simple equates this
95−with 'Data.Time.LocalTime', which has no concept of an offset. One can
96−convert between @timestamptz@ and @timestamp@ using the @AT TIME ZONE@
97−operator, whose semantics also demonstrates that @timestamptz@ is
98−'Data.Time.UTCTime' whereas @timestamp@ is 'Data.Time.LocalTime'.
99−
100−PostgreSQL's @timezone@ is a per-connection variable that by default is
101−initialized to @\'localtime\'@, which normally corresponds to the server's
102−time zone. However, this default can be modified on the server side for an
103−entire cluster, or on a per-user or per-database basis. Moreover, a client
104−can modify their instance of the variable at any time, and can apply that
105−change to the remaining duration of the connection, the current transaction,
106−or the execution context of a server-side function. In addition, upon
107−connection initialization, the libpq client checks for the existence of
108−the @PGTZ@ environment variable, and if it exists, modifies @timezone@
109−accordingly.
110−
111−With a few caveats, postgresql-simple is designed so that you can both send
112−and receive timestamps with the server and get a correct result, no matter
113−what the @timezone@ setting is. But it is important to understand the caveats:

115−1. The correctness of server-side computations can depend on the @timezone@
116− setting. Examples include adding an @interval@ to a @timestamptz@, or
117− type casting between @timestamp@ and @timestamptz@, or applying
118− the @DATE@ function to a @timestamptz@.
119−
120−2. The (localtime, offset) pair contained in a 'Data.Time.ZonedTime' result
121− will depend on the @timezone@ setting, although the result will always
122− represent the same instant in time regardless of the time zone.
123−
124−3. Sending a 'Data.Time.LocalTime' and interpreting it as a @timestamptz@
125− can be useful, as it will be converted to UTC via the tz database,
126− but correctness will depend on the @timezone@ setting. You may prefer
127− to use an explicit @AT TIME ZONE@ conversion instead, which would avoid
128− this contextual dependence.
129−
130−Furthermore, although these following points don't involve the @timezone@
131−setting, they are related to the last point above:
132−
133−1. Sending a 'Data.Time.UTCTime' and interpreting it as a @timestamp@ can
134− be useful. In practice, the most common context used to disambiguate
135− @timestamp@ is that it represents UTC, and this coding technique will
136− work as expected in this situation.
137−
138−2. Sending a 'Data.Time.ZonedTime' and interpreting it as a @timestamp@ is
139− almost always the wrong thing to do, as the offset will be ignored and
140− discarded. This is likely to lead to inconsistencies in the database,
141− and may lead to partial data loss.
142−
143−When dealing with local timestamps that refer to the future, it is often
144−useful to store it as a local time in a @timestamp@ column and store the
145−time zone in a second column. One reason to do this is so that you can
146−convert to UTC on the fly as needed, and be protected against future changes
147−to the TZ database due to changes in local time standards. In any case,
148−'Data.Time.ZonedTime' is not suitable for this application, because despite
149−its name, it represents an offset and not a time zone. Time zones can change;
150−offsets do not. In reality, we can't convert a local timestamp that occurs
151−sufficiently far in the future to UTC, because we don't know how to do it yet.
152−
153−There are a few limitations and caveats that one might need to be aware
154−of with the current implementation when dealing with older timestamps:
155−
156−For sufficiently old timestamps in almost all time zones, the IANA TZ
157−database specifies offsets from UTC that is not an integral number of
158−minutes. This corresponds to local mean time; that is, astronomical
159−time in the city that defines the time zone. Different time zones moved
160−away from local mean time to a standard time at different points in
161−history, so \"sufficiently old\" depends on the time zone in question.
162−
163−Thus, when retrieving a @timestamptz@ postgresql will in some cases
164−provide seconds in the offset. For example:
165−
166−@
167−$ psql
