I think that there's a need for additional built-in array functions, including one to succinctly test if an array has no elements. Iterating through an array with plpgsql, for example, is more clunky than it should be. -- Regards, Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
