Is there a bug in FOR i IN 1..10 LOOP (8.4.4)?
CREATE FUNCTION test() RETURNS text
LANGUAGE plpgsql
AS $$DECLARE
num_var TEXT;
BEGIN
FOR i IN 1..10 LOOP
num_var := num_var || ',' || i;
END LOOP;
RETURN num_var;
END;$$;
SELECT test();
returns NULL
Woops, figured it out. Just needed to declare the num_var := '';

What makes you think there is a bug? What does this function return for
you? It always helps us to see everything you have seen.
Without taking the time to try it on my system, I'd recommend explictly
converting your index to text:
num_var := num_var || ',' || i::text;
