Didn't test, but I think this:

    DECLARE my_cur  scroll CURSOR FOR
        SELECT test_rr() ;

needs to be more like

    DECLARE my_cur  scroll CURSOR FOR
        SELECT * FROM test_rr() ;

As you have it, the cursor produces a single composite column,
which isn't consistent with

    FETCH FROM my_cur INTO ret1, ret2, ret3, ret4, ret5 ;

I vaguely recall that plpgsql will sometimes let you be sloppy
about composites versus separate columns, but evidently not here.
