My basic idea was:
CREATE FUNCTION aaa(IN a1, OUT a, OUT b)
RETURNS SETOF RECORD AS $$
..
is similar
CREATE FUNCTION aaa(IN a1)
RETURNS SETOF RECORD AS $$
from executor perspective there isn't any difference. But PL languages have
to create only IN variables. It's protection before identifier's name
colision. With special flag I don't need any changes in executor. And small
change in PL compile rutines. Special proargmode can be solution too. I
don't need new column in pg_proc, but have to modify executor and need more
changes in output rutines in PL.
I'll go on the way to spec. proargmode. It's good idea.
Thank You
