* 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

* Fix issue with extra characters. Extra parens in valueList caused issues in mysql. Extra backticks in value reference names
* update changelog and bump version number
* Fix issue caused by toAliasReference failing to reindex an alias reference by its new alias source
* Add support for SqlExpr (Maybe (Entity a))) to aliasing in Experimental. Fix#193
* Update changelog with new PR name. Fix name shadowing in test.
* Fix binary operations(i.e. ==.) on aliased values.
* no need for version bump since 3.3.3.3 hasnt been released yet

* Test and further document ToBaseId
My coworker Lev was adding this typeclass to our codebase and we hadn't used it before. I added a little more documentation that I think would help clarify things, particularly what the point of the witness function was. More importantly I added a test for this typeclass.
* 3.3.3.2
* It works?
* Add multiple return values back in
* Allow order by alias
* Support groupBy and count, Returning value from a fromQuery now will make it into an alias
* Eliminate Alias type, TODO: finish implementing all the functions on Value for the alias constructors
* Add entity support to subqueries
* Cleanup duplication; Cleanup warnings and finish implementing all the cases for aliased values and entities.
* Cleanup fromQuery and add comments
* Modify EValueReference to support aliased entity fields instead of having to use opaque ERaw in field access
* Implement SQL Set Operations
* Add test to show novel use of fromQuery
* Cleanup unsafe case statements
* Add type annotations to helper queries to satisfy the typechecker on older GHC
* New syntax for joins, using placeholder names with ' in them to avoid name conflict with existing join types.
New api properly enforces Maybe on outer joins and requires an on clause for all joins in their construction.
* Add some more test queries using the new syntax
* Add test to verify that delete works with the new syntax
* Add cross join and implicit cross join using comma examples to test code for new from syntax
* Comment out use of CrossJoin in common tests since postgres cant handle it with the current implementation of the CrossJoin kind
* Add typeclass machinery to support the use of the old Join data types used in the existing from clause
* Fix bug with CrossJoin and add on_ syntax sugar
* move new from syntax into Database.Esqueleto.Experimental
* Merge subqueries and unions with the new join syntax, they all seem to play nicely together
* Cleanup somehow copies of ToAlias ended up staying in Internal and a swp file made it in to the branch.
* Fix compilation errors
* Swith tuple to using a TypeOperator
* Make operator only 2 characters
* added up to 8-tuple instances for ToMaybe, ToAlias, and ToAliasReference
* Add compiler error tests for new syntax to support making better errors
* Use closed data families to allow for catching missing on statements in joins.
* Convert ToAliasReferenceT to be a closed type family matching the other classes in the Experimental module
* added Esqueleto.Experimental documentation: added introduction and several examples of old vs. new syntax
* added more usage examples to module introduction; added documentation to SqlSetOperation, From, on, from, and (:&)
* Update (^.) to only treat natural keys with more than one component as ECompositeKey. Fixes#176.
* Update article metadata test to ensure the correct response was being returned instead of just check if an exception was thrown
* Add article metadata to cleanDB before deleting all articles to fix foreign key constraint errors
* Bump version number and add changelog entry
* Fix issue with ToMaybeT for Values, Maybe was going in the wrong place compared to the rest of the library. Add test to prove that Left joining into a subquery that returns a maybe flattens the maybe properly to avoid needing to call joinV.
* Fix common test for postgres, needed to add dogCounts to the group by since postgres is strict on only agregates for non grouped columns; I really need to set up a local postgresql
* Revert ToFromT changes. Only accept functions that return a SqlExpr (Value Bool) in ToFromT
* escaped use of '@' in TypeApplications in documentation
* Add more specific type signature to `on`
per parsonsmatt review suggestion. Improves type inference significantly.

* Move non postgres related functions out of postgres module to internal.
* add entry to changelog
* Update between so it works with SQL values
* Add support for composite keys in between clause
* Remove unused values from ERaw in construct
* Update unsafeSqlBinOp to handle composite keys and between to use >=., <=. and &&.
* Support composite keys in unsafeSqlBinOp correctly
* Updated changelog
* Update version number of between to 3.1.0
* 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
