I agree. Unfortunately, I think it's a non-trivial fix. I've also been wondering if we could avoid taking an AccessExclusiveLock on a newly created (temporary?) table. It seems like no one should be able to see it until commit, at which point we'd be releasing the lock anyway. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
