I think this is a fine idea, but that wording might not be much help to novices. Maybe "Adding missing FROM-clause entry for pg_language", or some such? In a situation where you've got subselects, it may not be immediately obvious which FROM list the entry got added to. I can't think of any simple way of identifying that, however :-( regards, tom lane
