As of RHEL 5.5, there is now an official postgresql84 package you can
easily load. What I would do in your situation is target upgrading from
8.1 to 8.4 initially, via the dump/reload method, with the main expected
problem being the type case changes already mentioned. I've saved a
number of good links on this general topic onto
http://wiki.postgresql.org/wiki/Version_History that should provide some
additional guidance if you read through them a bit.
By the time you get that done, 9.0 should be a better tested and stable
release, and you can do a quick binary upgrade from 8.4 to 9.0 using the
pg_upgrade utility.
