Actually, wait a second. We were smart enough to not send fsync requests in the first place for temp rels. But we were not smart enough to not call ForgetRelationFsyncRequests when deleting a temp rel, which made for an entirely useless scan through the pending-fsyncs table. So there could be win there, on top of not forwarding the actual unlink operation. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
