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)
