If you have a unique index on the table's OID column (as one would hope, else it's not good for much) then 8.1 and up will avoid assigning duplicate OIDs. There might be some performance glitches if you have very long runs of consecutive OIDs in the same table, though. 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
