Actually, as long as you're not changing major versions (ie: 8.0.x to
8.1.x) you'll be fine. What you can't do is change things like CPU
architecture (well, sometimes you can, sometimes you can't). Changing
OSes (ie: windows to unix) would also be questionable.
PostgreSQL does have some safeguards to make sure you don't end up
trashing your data should the binary formats of the database differ,
but this isn't something people do very often, so caveat emptor.
