I suppose replace {1,5} with {32,40} should work...the question is what is
so special about 32-40 and why a range instead of just saying 40? Does it
really matter if the final group is less than 32 (assuming every other
group was 40)?
SELECT regexp_matches[1] FROM regexp_matches('0123456789012','(.{1,5})','g')
Alter to taste.
