Yeah, this is a bug. I think what happened is: 1. Simon committed his patch to reduce lock levels. 2. Robert copied that lock level in his commit 4240e429d0c2d889d0cda23c618f94e12c13ade7 that refactored use of RangeVarGetRelid. 3. When I reverted most of Simon's change, it didn't occur to me to look for places that had copied the bad lock levels --- I was just looking at what his patch had done. I will fix this, and also do some looking to see if the bogus lock levels propagated anywhere else... regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
