I think this makes plenty of sense. However, something that occured to
me just now is that perhaps the right thing to do in the long term is to
put this message in errcontext and leave the "invalid value for XXX" as
the main error message. That would probably involve attaching a
errcontext callback and removing the complaint_level from this message
altogether, letting the outer caller deal with it. I'm not sure how
would GUC work if the assign hook did not raise an ERROR in the
interactive case though.
