The problem is that the 7.2 driver has a bug with understanding the
extra precision in the seconds. In 7.1 the database only really
supported 9.99 for precision, but 7.2 can support upto 9.999999. One
way to work around this problem is to create your columns with less
precision. So instead of:
create table foo (col_a timestamp)
use:
create table foo (col_a timestamp(2)) - where two is two decimal digits
of precision

I understand your reluctance, but 7.3 goes RC1 today. And I personally
feel that the 7.3 driver is better than the 7.2 version. And I am
currently running it on one production system. (Of course as a
maintainer of the driver I probably should be using in it production
before anyone else :-)

If you go the 7.3 route, use something more current thant beta3. There
have been some fixes since beta3, one of which is very important. I
will try to get RC1 builds posted to the website over the weekend, else
you can build from CVS.
