Sorry, I saw that you had changed this.

Here is a simple example that works as a function:

junk=# CREATE OR REPLACE FUNCTION x(INTEGER[])
  RETURNS SETOF INTEGER LANGUAGE 'plpgsql' AS '
DECLARE
  i   RECORD;
BEGIN
  FOR i IN SELECT f1 FROM ci WHERE f1 = ANY ($1) LOOP
    RETURN NEXT i.f1;
  END LOOP;
  RETURN;
END;';

junk=# select * from x('{1,2,3,4,5,6,7,8}');
 x
---
 2
 6
 1
 8
(4 rows)
