Re: "RETURNS SETOF" function question

There was an article that covered this in the Postgres Online Journal
(http://www.postgresonline.com/journal/index.php?/categories/6-pl-programming).  Basically, do this:

CREATE OR REPLACE FUNCTION foo(text, text)
       RETURNS SETOF text
$$
       SELECT * FROM foo($1, $2);
$$
LANGUAGE sql;
