This sounds very much like transaction Id wraparound, meaning you failed to vacuum pg_class (and possibly other system catalogs as well) in a timely fashion. Basically you need to return the transaction counter a little bit, then vacuum and make sure all your data is still consistent. This has been discussed before. See for example: http://archives.postgresql.org/pgsql-bugs/2005-05/msg00079.php -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.
