A bigger problem is that doing anything like this will require reversing the logical path of causation in EXECUTE USING. Right now, we evaluate the USING expressions first, and then their types feed forward into parsing the EXECUTE string. What Heikki is suggesting requires reversing that, at least to some extent. I'm not convinced it's possible without breaking other cases that are more important. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
