select distinct on

Hello,

I am trying to use SELECT DISTINCT ON.  This works as intended:
    SELECT DISTINCT ON (f1) * from table ORDER BY f1

 f1 | f2 | f3
----+----+----
  1 |  2 |  3
  2 |  2 |  2
  3 |  1 |  2

However, I am trying to order the results by non-distinct fields f2, f3
to get:

 f1 | f2 | f3
----+----+----
  3 |  1 |  2
  2 |  2 |  2
  1 |  2 |  3

Clearly this does not work:
    SELECT DISTINCT ON (f1) * from table ORDER BY f2, f3, f1

So is there some other way without SELECT INTO a temporary table?
Thanks in advance.
Dave
