Upgrade methods.

Hi,

What's the best way to upgade PostgreSQL on say a 6 machine cluster.

As I have compiled Pg from source must I compile Pg on each machine
again by hand
or can I compile once and send a package, .deb/.rpm, to each machine ?

Lets say all 6 machines have identical hardware and are all on a
192.168.0.0/24 Network.

Thanks
Regards Rudi.
