So it sounds like you haven't actually created anything in the 9.1
cluster yet?  If that is true, I owuld configure the 9.1 cluster to
use a different port.  It also needs to have a different data
directory, but if it is startign up OK when there is no port
collision, that must already be covered.  I would start both, and
run pg_dumpall (from the bin directory for 9.1) to dump the 8.4
cluster and pipe the output to the 9.1 server.
