*yeah* sure you're right. I shortened it to much^^

It is not about such a simple example. When joining tables (especially
with outer joins) it isn't trivial ;)

Thanks, I think this is what I've searched for (btw. we use 7.3). But
what I want to do is:
CREATE FUNCTION active(char) RETURNS setof $1 AS '
SELECT * FROM $1 WHERE status>-1;
' LANGUAGE SQL;
But this does not work. So I'll use views instead ;) It also should be
more performant. Thanks...
