It strikes me that the recently identified bug in pg_upgrade about not fixing the datfrozenxid of template0 might possibly explain this. You'd need to have upgraded an installation that was at least a couple billion transactions old to hit that bug. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
