From your URL email, this one seems to work:

select age(date '1999-05-17', date '1957-06-13');
age
-------------------------------
41 years 11 mons 3 days 23:00
(1 row)

This one did not:

peter=# select date '1999-08-13' - date '1999-06-13';
?column?
----------
61
(1 row)

and this one is less than one month:

peter=# select age(date '1999-05-17', date '1999-06-13');
age
----------
-27 days
(1 row)

I will admit age() is a little confusing, but it seems to work as
intended.
