Day Light Savings Problem

Hi,

As per this article
http://people.planetpostgresql.org/greg/index.php?url=archives/96-Is-your-database-ready-for-the-Daylight-Savings-Times-change-of-2007.html&serendipity[cview]=linear#comments,
My postgres 8.0.2 database has a problem with the new day light savings
time change this month.

So, I upgraded it to the latest 8.0 version which is 8.0.12 and below
you will see the output of the case statement and also the timezone
file. As you can see the case statement says that timezone value is
fixed but where as the timezone file still has the old values.

Is this a bug ? why cant it show the new timezone values in the
timezone file ? I even looked at the 8.2.1 timezone file it also has
the old values.

Can I use this postgres 8.0.12 version for the day light savings
problem.
