I don't think that quite works, because the standby might assign a relfilenode number for a global temp table and then the master might subsequently assign the same relfilenode number to a regular table. We might be able to make that not matter, but it's far from obvious to me that there are no gotchas there... ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
