Now I am the one that is confused. In the first example the three SELECT statements are each a transaction. In the second case you have wrapped them in one transaction. In either case they are still acquiring an AccessShareLock. I thought the issue was with an ALTER TABLE statement not UPDATES/DELETES. -- Adrian Klaver akla...@comcast.net -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
