When using an explicit cast to char(1) when refering to the
osm_type column postgres won't use the index in some cases.
Observed only on postgres 9.5 from the original Postgres
reporsitories.
Fixes#741.
Pyosmium comes with convenient functions for finding the
right state and does not require external files for
rembering the state. Updates can now conveniently
set up by simply running ./utils/update.php --init-updates
and state is kept directly in the import_status table.
This change requires an update in the database schema.
Run the following to update:
ALTER TABLE import_status ADD COLUMN sequence_id integer;
ALTER TABLE import_status ADD COLUMN indexed boolean;
ALTER TABLE import_osmosis_log ADD COLUMN batchseq integer;
Rank 30 has some very large geometries (peninsulas, time zones,
etc.) for which a near feature search for the full geometry is
too expensive, so do the search on the centroid only.
Derived columns are not needed because parent information is
always computed from scratch. So the columns are just duplicate
information.
Also get address information on nodes from address columns. The
other columns are not necessarily reliable when the node have not
been indexed yet.
* ERROR: sequence "seq_postcodes" does not exist
* ERROR: table "import_polygon_error" does not exist
* ERROR: table "import_polygon_delete" does not exist
* ERROR: sequence "file" does not exist
When roads cross boundaries, both administrative entities should
be added to the address list, so that both entities can be used
for searching. Also allows in a second step to better sort out
addresses of POIs on such roads.
Fixes#121.
The interpolaton computation needs information from the osm2pgsql
slim tables which may not be available when the data is inserted.
Insertion now only adds a line with basic address information to
location_property_osmline. The line is then split during the
indexing, leading to more lines (which are complete in that case)
being inserted.
Fixes#598.
If a country boundary has a country_code that is unknown to
Nominatim, it would delete all names because the coalascing
with country_name would not yield any result.
On placex_update we stop the indexing to the first parent if the rank_search is above 27. We should do the same check in get_adressdata, because place with a rank_address != 30 and a search_rank > 27 will have only 1 parent.

interpolation lines may be missing in osmline when the interpolation
is broken, so we cannot conclude that a way is not in place, just
because there are no entries in location_property_osmline.
It is perfectly valid that interpolated addresses refer to
something else than a street.
Also gets rid of the maximum interpolation size. As we don't
expand, arbitrary sizes are fine.
