I'd like to see us *not* overload "opaque" with yet another meaning;
see past rants on subject.  But as long as there was a distinguishable
representation of "returns void" in pg_proc, I'd see no problem with the
above.

plpgsql presently spells "CALL" as "PERFORM"; should we stick with that
precedent?
