Ah, you want it for aggbasetype in pg_aggregate, I did not
see that.
How could we then disallow it's use in other context ? Seems
if there is no restriction, "any" will be exactly as prone to
"wrong use" as opaque was.
May be a plan could be to leave opaque, but throw a notice
when it is used in a create stmt, like:
NOTICE: the use of type OPAQUE should be avoided where possible
