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
