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).
