Yeah but we already have this problem. Right now, it typically happens because of some statement of the form SELECT ... AS ...; this just adds one more case where it can happen, and I doubt it's any more common than the case we already struggle with. But at any rate Tom is planning a fix for 8.5, so I don't think there's any need to get excited just yet. If Tom doesn't get his stuff finished by January, we can revisit the issue then. ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
