Is 1852615815 anywhere near the range of existing OIDs in pg_class? > If I look up for this oid in pg_class I don?t find it, but I do find it in > pg_depend. Is that normal ? No --- at least not when the classid says it's a pg_class OID, as it does here. Do you find any pg_depend rows with refobjid = 1852615815? What about other rows mentioning OID 111893? Is that OID present in pg_namespace? (The 2615 says it's a pg_namespace OID.) We have seen some previous reports suggesting that once in awhile not all the catalog entries associated with temp tables get cleaned out at backend exit. I'm not sure the cause has ever been conclusively identified, though if memory serves we have fixed a bug or two that *might* explain it. If 1852615815 doesn't seem to be a legitimate OID, it's also possible that this is just data corruption in pg_depend. If you can't find any evidence of other issues, it might be reasonable to conclude that the pg_depend row is leftover junk and delete it manually. But you should make real sure nothing is linked to it first. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
