Yeah, we should do something with that.  Are people okay with the idea
of CREATE LANGUAGE, etc, retroactively changing prorettype from OPAQUE
to the correct thing?

All but the inet/macaddr->text change; I backed that out after finding
that it induced a bunch of regression-test failures.  The tests assume
that "inet = integer" will provoke a failure.  Guess what: if both inet
and integer have implicit casts to text, the system takes it.

On reflection I still feel that we should be getting rid of implicit
casts to text rather than adding more.  This is still an open bug:
