Is there a way to define the SETOF record on the fly, like you do with 
RETURNS TABLE (f1 type1, f2 type2)?

Doesn't RETURNS TABLE meet the need already?

That rationale means that RETURN SETOF is not needed, and can be removed from Pg, since "RETURNS TABLE meet the need already".

But of course there are times when RETURN SETOF is useful.

So... can ad hoc SETOF definitions be created in the function definition, or is CREATE TYPE the only way to do it?
