yeah. maybe though you might find that the overhead of temp tables is already pretty good -- they are mostly ram based in typical usage as they aren't synced. I find actually the greatest overhead in terms of using them is creation and dropping -- so for very low latency transactions I use a unlogged permanent table with value returned by txid_current() as the leading field in the key. merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
