Ignore pseudo-system objects in table list

These objects are created by turning on replication and they have column types (sysname, xml) that are not supported by Doctrine. 

According to Microsoft's support, these are "'pseudo-system' object[s]" that appear in the User Table type instead of the System Table type.

Exclude tables with table_type of VIEW

tests to come

Disallow empty delete criteria on the connection

MasterSlaveConnection::close() should reset connections array

Fixed undefined index notice when attempting to reconnect a MasterSlaveConnection after close has called

This excludes views registered by PostGIS 2.x like geography_columns, geometry_columns, raster_columns and raster_overviews.
The table_name != 'geometry_columns' is kept for PostGIS 1.5 compatibility. The type changed to VIEW in PostGIS 2.0.
