It can also be a very time consuming process. It often also involves
having to juggle resources around, find extra disk space floating around
somewhere to build extra replicas, or abandon your fail over target for
a period of time while upgrade that.
BTW, the trigger issue goes away with 8.3 and Slony 2.0.
