I've tried to upgrade a large production database from 9.2.4 to 9.3.2 using pg_upgradecluster (using pg_upgrade method) and it fails with the error below. Upgrade using dump/restore seems to work on a test system but would require a too long downtime on the production system. # pg_upgradecluster --method=upgrade 9.2 main /data/postgresql/9.3/main [...] Removing support functions from new cluster ok Copying user relation files /data/postgresql/9.2/main/base/12034/7174572 Mismatch of relation OID in database "rg_www": old OID 22046, new OID 17671 Failure, exiting Error: pg_upgrade run failed [...] Any thoughts? How can this be fixed? Regards, SW. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
