* Get PKcols inside tables - done with SQL for tables and
with an additional step in Haskell for views.
This fixes an fk column being considered as a pk column on views
and corrects the test added on

* classify view key dependencies in SQL
* remove Column from Relationship
* Merge cols/fcols in Relationship and
ensure allM2ORels and allViewsKeyDependencies fk columns
are ordered - done by attnum in SQL
* Cardinality now contains relColumns instead of Relationship -
this simplifies getJoinConditions.
Just having the QualifiedIdentifier gets us closer to having
Relationship as a Table attribute since it avoids a cyclic dependency
* remove unnecessary findTable
* modify RootSpec test
Using GET with text/plain or application/octet-stream as Content-Type headers no longer returns 404 Not Found when a function with no parameters exists
Aggregates and Window functions can't be called as RPCs in a useful way.
Procedures are not supported right now, but might be added later.

The PG version is only read by the Connection Worker, which is not used in the case dump-schema. Now, the pg version is read in the schema cache queries directly, avoiding this problem in all cases.
