What is it that you are trying to accomplish?

Assuming it is to return a set of rows, would something like the below work:

CREATE OR REPLACE FUNCTION fn_plpgsqltestmulti(
param_subject varchar,
OUT test_id integer,
OUT test_stuff text)
RETURNS SETOF record
AS
$$
BEGIN
FOR i IN 1..10 LOOP
test_id = i;
test_stuff = i::text || '_stuff';
RETURN NEXT;
END LOOP;
END;
$$
LANGUAGE 'plpgsql' VOLATILE;

test=> select * from fn_plpgsqltestmulti('123');
test_id | test_stuff
---------+------------
1 | 1_stuff
2 | 2_stuff
3 | 3_stuff
4 | 4_stuff
5 | 5_stuff
6 | 6_stuff
7 | 7_stuff
8 | 8_stuff
9 | 9_stuff
10 | 10_stuff
(10 rows)
