I need to upgrade my postgresql server, and I'm curious what the best path to get to 8.4 or 9.0 might be.
I see a lot of upgrade guides from one major release to the next major release, and I am curious if I need to do this one release at a time, or is there a shorter path to get to the latest version.
Is there a list of changes to data types that might help me determine any incompatibilities that might be an issue (if any)?
Any help on this would be greatly appreciated.
