missing table identifier added

If the database have different schemes, with objects, that the actual logged in user has no rights, the existing statements will collect all objects (sequences and tables) and try to read them in later steps. This will throws exceptions. The reason for that is the fact, that both procedures getListSequencesList() and getListTablesSQL() will receive all known database objects from postgres catalogs. But the actual logged-in user, maby has no read permissions to object inside other scheme-owner. The additional parts inside both sql-statements will reduce the result to only objects that the user are able to see.

Add unit test to check boolean conversion with and without PDO boolean type

Add functional test to check null conversion with boolean type. This test required NULL to be allowed in the table column.

Add new line after an IF statement to be consistent with the coding standard

The inner connection should be unreferenced, but the property should not be removed from the object

As seen here => http://technet.microsoft.com/en-us/library/cc626307(v=sql.105).aspx

TimeType resets date fields (i.e. unused DateTime object fields) to UNIX
epoch (1970-01-01). This makes TIME field mapping stabe (i.e. same time
will be always mapped to the same DateTime fields).

See DDC-179 (similar issue with DateType). Fixes DBAL-993.
