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 regards Pavel Stehule 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? regards Pavel Stehule -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
