First. I write bigger C library - implementation of some dbms_packages and
plvision packages. I don't expect using plpgsql. I have a lot of void
functions. Usually set_...unset_ with and I need sql language for createing
wrappers for default values.  That's all.
Second. The logic in PostgreSQL is wrong now. Is too hard and too simple. I
can get VOID value via SELECT void function too.
