Track variable uses within query validation for caching (fix #3097) (#3135)
This fix is a little ugly, but it’s the only simple solution without a
significant refactoring that restructures the relationship between
GraphQL/Validate and GraphQL/Resolve. The ugliness should go away if we
implement something like #2801.

54e6439579 Change the way we determine whether or not queries are reusable
This fixes an issue where queries could incorrectly be considered
reusable if a variable was used in two positions: one where it affected
SQL generation and one where it did not.

ed26da59a6 Add support for GraphQL enum types via enum table references
These changes also add a new type, PGColumnType, between PGColInfo and
PGScalarType, and they process PGRawColumnType values into PGColumnType
values during schema cache generation.

multiplexed subscriptions (#1934)
* add types to represent unparsed http gql requests

This will help when we add caching of frequently used ASTs

* query plan caching

* move livequery to execute

* add multiplexed module

* don't issue a transaction for a query

* don't use current setting for explained sql

* move postgres related types to a different module

* validate variableValues on postgres before multiplexing subs

* don't user current_setting for queries over ws

* plan_cache is only visible when developer flag is enabled

* introduce 'batch size' when multiplexing subscriptions

* bump stackage to 13.16

* fix schema_stitching test case error code

* store hashes instead of actual responses for subscriptions

* internal api to dump subscriptions state

* remove PlanCache from SchemaCacheRef

* allow live query options to be configured on server startup

* capture metrics for multiplexed subscriptions

* more metrics captured for multiplexed subs

* switch to tvar based hashmap for faster snapshotting

* livequery modules do not expose internal details

* fix typo in live query env vars

* switch to hasura's pg-client-hs

fix sql generation for boolean expressions, closes #853 (#1037)
When using self referential relationships in boolean expressions, the exists clause incorrectly uses the table names to qualify columns which will be the same for parent table and the child table. This is now fixed by generating unique aliases as we traverse down the relationships.
