yes. except (global) temp tables can: *) be updated with data not derived from permanent tables (think: session management, etc) *) outlive a single transaction *) be indexed independently of the sourcing tables *) be referred to from multiple queries (you can simulate this with CTE, but that approach obviously has limits) of course, temp tables that would 'just work' would be wonderful. merlin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
