On reflection I think it makes no sense at all to leave those tools
issuing CREATE/DROP LANGUAGE.  We want to move people over to managing
languages via extensions, and leaving those tools unchanged will not
serve that goal.  However, I don't mind labeling them as deprecated
and not troubling to point out that they could be used for installing
non-PL extensions.
