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 :-(
