I looked on possibilities in gram.y and I thing, type identifiers
"ANY TYPE" is possible without any problems (this should be synonym for "any"),
"SAME AS" needs add "same" keyword to col_name_keywords , i.e. "same"
is prohibited for function names - it should be a problem

I found so pgparser provide some ref type syntax via % symbol. So we
can use following syntax:
CREATE OR REPLACE FUNCTION foo(a ANY TYPE, b a%TYPE)
RETURNS a%TYPE ...
It is not pretty like SAME AS, but I am sure, so this is doable
(parser knows it now)
any other ideas?
