Yes it is possible. You can setup new version of postgresql with new
data directory, in different location (say /var/pg_new/data), run it
on different port, and have multiple postgresql installations running
side by side.
What OS do you run, and where do you get postgresql binaries from.

Probably this will work for us.  We are using RedHat and I think that we may
be getting binaries from a couple of sources.
