* Initial attempt at Lateral joins
* Fix lateral queries for Inner and Left joins. Remove for Full and Right as this is apparently illegal(who knew). Add TypeError on Full and Right joins. Update on clause to use a custom constraint instead of relying on ToFrom.
* Fix typo leading to erroneous ToFrom instance
* Implement non-recursive CTE's
* add withRecursive; cleanup whitespace
* Fix multiple recursive CTEs. Apparently the spec just wants RECURSIVE if any of the queries are recursive.
* Add test to verify that a CTE can reference a previously defined CTE
* Update with/Recursive to return an element of a from clause to allow for joins against CTEs
* Modify set operations to use a custom data type + typeclass + typefamily to allow direct use of SqlQuery a in set operation and to allow recursive cte's to unify syntax with SqlSetOperation. Added lowercase names for set operations. If we can migrate off the constructor names we may be able to simplify the implementation.
* Fixed haddock documentation issue from v3.3.4.0 and added documentation
for new features introduced by v3.4.0.0
* fixed comments that were changed while debugging haddock build
* Cleanup formatting in From per PR. Cleanup ValidOnClause, added documentation and reduced the number of instances
* Update src/Database/Esqueleto/Experimental.hs

* Move non postgres related functions out of postgres module to internal.
* add entry to changelog
* added PostgreSQL.JSON module
* finished adding all JSON operators
* cleanup
* half way through writing tests
* final tweaks to comments
* finished with JSON tests
* upped persistent dependency to 2.10.0 because of PersistArray data constructor addition needed for JSON operators
* noticed the minus operator with text[] as right operand was only added in PSQL v10, added function and adjusted types/tests
* adjusted yaml configs for updated dependencies and PSQL v10 in Travis
* try to get PostgreSQL 10 running
* use @since notation
* removed postgresql from 'services' field
* and one more time, with FEELING! (and postgresql-10)
* foo
* PSQL 10 runs on 5433, it seems? reverting .travis.yml changes and setting test conn to port 5433
* of course I forget to add the PORT env > .<
* doop-dee-doo
* herp-a-derp
* last commit (hopefully)
* also have more recent dependencies in the 'compiler should error' tests
* why does it feel like this'll go on for a while still?
* copied some extra-deps from the persistent ymls
* aaaaand we're done... right?
* added persistent-postgresql to the dependencies and used its instances for Aeson.Value
* small comment fix
* moved the instances to their own module, this way they're optional to use if you don't use persistent-postgresql
* use port 5432, like a normal PostgreSQL!
* added JSONB newtype with instances, instead of orphaning Aeson.Value
* reworked everything to use the JSONB newtype. And adjusted most comments to reflect the change
* fixed all the tests (just making it compile again)
* that's right, Travis' PSQL v10 NEEEEDS it to be port 5433... for some reason
* update on the haddockumentation
* added JSONAccessor data type for easier usage of certain operators
* Also add to changelog.md
* JSONExpr -> JSONBExpr
* this damn PGPORT is really irritating
Aggregate functions like array_agg and string_agg will return NULL instead of
empty arrays and empty strings resp. when run on zero rows. This change reflects
that in the haskell types. It also adds a "maybeArray" function that
coalesces NULL into an empty array, because currently there is no way to write
an empty array literal (`val []` does not work)
