In the first place, it's unlikely that there'd be a huge run of consecutive OIDs *in the same table*. In the second place, if he does have such runs, the claim that he can't possibly have dealt with OID wraparound before seems pretty untenable --- he's obviously been eating lots of OIDs. But having said that, there isn't any real harm in fixing the OID counter to match what it was. You need to run pg_resetxlog to set the WAL position and XID counter anyway, and it can set the OID counter too. 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
