Title: Changed PostgreSQL's getTableColumns.

Now returns object with "Default" property instead of "default", as MySQL and other driver does.
Changed corresponding test.

Added conversion between PostgreSQL's null to PHP's null value, default field containing "NULL::character varying" will be used as string otherwise.
