You're looking for to_char(): http://www.postgresql.org/docs/9.1/static/functions-formatting.html Something like this ought to do what you want: select to_char(12345678, 'FM999,999,990'); Each 9 in the formatting pattern will output a digit only if there's a corresponding one in the number; and the FM trims off any padding spaces. Just make sure you have enough 9s in the pattern for any possible number you'll encounter.
