Oh. For some reason I thought that would still be possible. I don't think it's worth designing a whole new PL/pgsql language construct just to support this feature. Given that this should be a relatively unusual type of function, asking people to write them in C doesn't seem unreasonable. ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
