contrib/rtree_gist is moved to PostgreSQL core !

Jun 27, 2005

GiST is now concurrent !

full concurrency for insert/update/select/vacuum:
        - select and vacuum never locks more than one page simultaneously
        - select (gettuple) hasn't any lock across it's calls
        - insert never locks more than two page simultaneously:
                - during search of leaf to insert it locks only one page simultaneously
                - while walk upward to the root it locked only parent (maybe non-direct parent) and child. 
		   One of them X-lock, another may be S- or X-lock
- 'vacuum full' locks index
- improve gistgetmulti
- simplify XLOG records
