I know that. I have to check the period (dates entered by user) must be
correct and must be perfectly divisible by the interval given. This is a
pre-check for the interest calculation.
If user enters '01/04/2010' and '15/05/2010' as the dates, and interval
as 'month' then, there are 15 days left and if the banking product is
set to calculate interest for a complete month only, then calculation
can result in wrong interest figures. So I have to check if given period
is perfectly divisible by the interval or not.
I changed the dates to match my date_style.
test=> select age('05/15/2010'::date ,'04/01/2010'::date)
test-> ;
age
---------------
1 mon 14 days
(1 row)
test=> select date_part('days', age('05/15/2010'::date
,'04/01/2010'::date));
date_part

test=> select age('06/01/2010'::date ,'04/01/2010'::date)

test=> select date_part('days', age('06/01/2010'::date
