Fix for DBAL-82

Filter table columns by owner

[DBAL-138] Connection::quote now supports both DBAL and PDO types

DDC-1282 - Remove overprotective casting of days/months to integer, which prevents passing columns as days. The platform is not responsible for escapsing, the DQL parser already does it way before generating the sql statements.

DDC-1271 - Fix date diff in PostgreSQL when timestamps are passed by casting everything into dates explicitly.

Fixed: MySQL Driver didn't return Database name if DBAL was initialized using existing PDO instance

Writing the result into the output object instead of just echoing it out.

Support for Postgres SET NULL, SET DEFAULT, and NO ACTION foreign key detection in the PostgresSQLSchema Manager

OCI8 Change private properties and methods to protected.

DBAL-126 - Fix bug during table diffs when creating new primary keys, unique constraints were created instead.

Change Oracle "drop column" syntax
