Tom's major recommendation is to move up to the latest 7.2 release -
which, while currently unsupported, contains a number of BIG bugfixes
relating to data integrity. (IIRC the version number is 7.2.5). You
should be able to install packages or build from source and install in
place without any changes to your code. Getting a dump of your data
beforehand is always a good idea Just In Case, but it shouldn't be
necessary most of the time.

Jumping between "major" versions (eg, 7.2->7.3) is where there are
changes to data types and the back-end storage; for a major version
change the usual recommendation is to dump and reload.

Check back through the list archives; this general recommendation ("For
PG version x.x.n, always run the latest point-release (n) for any given
major version (x.x)") has been posted quite a few times over this past
year alone.
