Yeah, that's what I was thinking too. If you needed to change more
than just the topmost SELECT list, you'd need two steps: an ADD COLUMN
and then CREATE OR REPLACE VIEW to change the query in some way that
doesn't result in changing the output column set. Maybe that's going
to be too awkward to use though.
