I've never heard of doing it that way, but I'm very interestes in
seeing how it is done.  This is what i've tried so far, but am still
getting the cross join:

postgres=#
select * from generate_series(1,3)
CROSS JOIN  ( values('a'),('b'),('c') ) as myvals( letter )
OFFSET 0;

 generate_series | letter
-----------------+--------
               1 | a
               2 | a
               3 | a
               1 | b
               2 | b
               3 | b
               1 | c
               2 | c
               3 | c
(9 rows)
