SQL functions are inlined when invoked, and so must be valid subselects.
rewrite it in plpgsql.
CREATE OR REPLACE FUNCTION add_user (TEXT, TEXT, TEXT, TEXT)
RETURNS usr AS $$
DECLARE
retval usr;
BEGIN
INSERT INTO usr (login,pass,name,email) VALUES ($1,$2,$3,$4)
RETURNING usr.* INTO retval;
RETURN retval;
END;
$$ LANGUAGE PLPGSQL SECURITY DEFINER;
