I am now thinking no documentation paragraph is even needed. We have to
use the number of months in the earlier date or simple computations
would not work like:
test=> select age('2004-05-29', '2004-06-28');
age
----------
-30 days
(1 row)
The end of the earlier month is part of the interval between the two
timestamps, while the end of the later month is not. Of course with a
multi-months span there are more chances for variance, but we certainly
should give the right answer for an interval < 1 month. I can just add
a C comment.
