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.
