Unfortunately we haven't prepared release notes yet. If you want to do
testing, what I would look for is performance changes. The main stuff
in 8.0.2 (other than bugfixes for very specific bugs) is:
* Replace ARC buffer management algorithm by 2Q to avoid pending IBM patent.
Testing so far says this causes a few percent degradation in some
cases and no visible impact in others. We'd be interested to hear
more reports.
* Planner tweaks to avoid bad side-effects of the 8.0 change that made
the planner use the current physical table size instead of what
pg_class.relpages says. That's usually a win but caused problems if
a plan is cached when the table is first created (and so is empty).
