This was limit in older version
you have to assign values to these variables and call RETURN NEXT without
any parameters
CREATE OR REPLACE FUNCTION public.foob(OUT a integer, OUT b integer)
RETURNS SETOF record
LANGUAGE plpgsql
AS $function$
BEGIN
a := 10; b := 20;
RETURN NEXT;
b := 30;
RETURN NEXT;
END;
$function$
result
┌────┬────┐
│ a │ b │
╞════╪════╡
│ 10 │ 20 │
│ 10 │ 30 │
└────┴────┘
(2 rows)
