It's just an oversight.
What about the similar program
create or replace function ffa(int, int) returns int language plpgsql as $$
DECLARE a ALIAS FOR $1; a ALIAS FOR $2;
begin return a + a;
end;
$$;
I think ffa(a int, a int) should give an error but I don't know if the
ALIAS example above should (or even if it does, I don't have a pg
installation here to try it).
