issue2550853 - better error handling and cleanup on some postgres tests by Stuart McGraw. My postgres tests passed both before and after I applied his patch, but the code change seems rational. issue2086536 - back_postgresql: fixing pg_command and prefering psycopg2. Patch done by Philipp Gortan (mephinet). His patch also improves handling of retryable errors. Applied and edited by John Rouillard. Edits included removing support for psycopg1. See: https://sourceforge.net/p/roundup/mailman/message/32855027/ for rational for dropping it Again all 137 postgres tests pass.
