First, I'd recommend updating your 8.1.x install to 8.1.11 or whatever
the latest is right now.
There are some ugly bugs hiding in 8.1.3 if I remember correctly (Tom
just mentioned one that could do things like leaving orphaned objects
in the db in another thread.) It's always a good idea to keep up to
date on the updates of pgsql. Some updates aren't critical, but most
early ones in the 7.x through 8.1 tended to have a lot of bugs fixed
in them in the first few updates.
Then, your migration to 8.3.x can be done a bit more leisurely and
well planned and tested, without putting your current data in danger.
