I would say the biggest impact from 7.2 to 7.3 are:
- Schemas and their support
- Indexing issues related to using C locale or anything else
- The less greedy type matching changes result in some indexes being
ignored that were once used.
- Old sequences and other things won't inherit dependency. not a real
problem, just an fyi.
From 7.3 to 7.4 the biggest changes planned so far:
- windows native support <-- gartner gives it a 90% chance of making it
into the main disto... :-)
- fix for in() performance issue <-- already in CVS tip
- partitioning or tablespaces <-- who know? seriously, who?
- vacuum will be able to compact out unused space <-- Tom Lane
- possible newer settings for the default postgresql.conf could
increase load on some machines to a point they may need to be reconfigured
to come up.
Data wise I don't think there's gonna be a lot that will mess up a 7.3 to
7.4 conversion so far that's gone by.
