So, what do you want to work on? Let me know, I'll do as much match-making at the conference as I can.
Here is my list:
* Additional approximate string matching functions and index access for them using gin/gist/spgist.
* Signature indexing with gist/spgist in various fields. For example, indexing of image signatures with similar images retreival.
* Statistics collection and selectivity estimation for geometric datatypes.

With best regards,
