Обсуждение: SQL FUNCTION return type on INSERT

What value should I RETURN for a SQL FUNCTION that contains an INSERT
statement?

I've just looked at the new online 7.2 documentation and found that all
functions must end in some kind of select.
How about this then?

CREATE FUNCTION foo(varchar)
RETURN unknown
AS '     INSERT INTO footable VALUES ($1);     SELECT null; '
LANGUAGE 'sql';
