There are bugs in the 8.3.1 release which bit us when we started using it; however, these are fixed in the 8.3 stable branch of cvs. We are running successfully with that. These fixes will be in 8.3.2 when it is released. http://archives.postgresql.org/pgsql-bugs/2008-04/msg00168.php It's generally a good idea to test with a new release before putting it into production, especially a major release. Since you asked on the performance list -- we have found performance to be significantly better under 8.3 than earlier releases. Also, the data takes less space on the disk, and checkpoint disk activity spikes are reduced in 8.3. -Kevin
