Something like PITR could be interesting, as there is already a patch
that starts the work, the extra credit would be to take the existing
patch and actually make it work.

While some form of bitmapped indexing would be cool, other ideas might
be to implement different buffer manager strategies. I was impressed by
how quickly Jan was able to implement ARC over LRU, but there are a host
of other strategies that could also be implemented. 

I think there are other good projects in there, like allowing indexes
for searching nulls, or adding concurrency to GIST, or allowing non
btree indexes to handle unique's
