- Updated capabilities for PostgreSQL in server.cfg - Updated test-ATIS & test-table-elimination to work with PostgreSQL - Updated test-transaction test to also work with non transactional tables Other things: - Added test of tables with many keys in test-insert - Added 2 new GROUP BY .. ORDER BY test
