Re: Function working in PostgreSQL 8.3.6 and not in 7.4.8

Thanks, that was it indeed :D
I found it in the documentation only after your post.

Here's the modified function working with 7.4.8, in case somebody would like to know:
CREATE OR REPLACE FUNCTION subcategories(int) RETURNS setof int AS '
DECLARE
    -- declarations
    category        ALIAS FOR $1;
    category_current    record;
    sub_category_current    record;
BEGIN
    -- function body
    SELECT category as my_output INTO category_current;
    RETURN NEXT category_current.my_output;
    FOR category_current IN SELECT id FROM is_categories WHERE id_parent=category AND status=''1'' LOOP
        FOR sub_category_current IN SELECT subcategories FROM subcategories(category_current.id) LOOP
            RETURN NEXT sub_category_current.subcategories;
        END LOOP;
    END LOOP;
    RETURN;
END;
' LANGUAGE plpgsql;

Thanks again :)
