* Create a background process for each database that runs while
database is idle, finding superceeded rows, gathering stats and vacuuming
* Add UNIQUE capability to non-btree indexes

* Improve Subplan list handling
* Allow Subplans to use efficient joins(hash, merge) with upper variable
* use fmgr_info()/fmgr_faddr() instead of fmgr() calls in high-traffic
places, like GROUP BY, UNIQUE, index processing, etc.
* improve dynamic memory allocation by introducing tuple-context memory
allocation
* add pooled memory allocation where allocations are freed only as a group
