no...

The short version:

Any 7.x PG: uses your OS's timezone info, hence OK if you've

updated the OS

8.0.x PG: need 8.0.4 or later

8.1.x PG: all releases know about 2007 USDSTupdates

8.2.x PG: all releases know about 2007 USDSTupdates

I'm curious. For 7.4.x, does the database require a restart for the
change to take effect? I'm aware of a few production installations
where the OS changed, but postgres time functions didn't take hold.

Yes, probably. On those systems you will likely also find cron and
other time-sensitive subsystems in need of a restart ...
