Thought I would do a poll of what is happening in the world for 8.3. I have:

Alvaro Herrera: Autovacuum improvements (maintenance window etc..)
Gavin Sherry: Bitmap Indexes (on disk), possible basic Window functions

Gavin: how's it going with the bitmap indexes? I could work on it as well, but I don't want to step on your toes.

Heikki Linnakangas: Working on Vacuum for Bitmap Indexes?

* Grouped Index Tuples ( I don't know how to proceed with this, but it's a feature I'd like to get in 8.3. Suggestions, anyone? I haven't received much comments on the design or code...

* vacuum enhancements, not sure what exactly..

* Plan invalidation, possibly. Tom had plans on this as well.
