Timezones are implemented using timezones files which contain info
about daylight savings since forever. When/if the change happens a new
set of timezone files should be released. Copy over the one for your
area and you're fine.
Postgresql may use it's own system, I think it depends on the version.
But the same principle applies.
This I what I did when Sydney moved the daylight savings for the
Olympics. I got the file and copied it to all my linux machines. OTOH
the windows machines I never worked out how to do it...
Hope this helps,
