* Don't do cube with type support Eventually, there is different ways of reducing R-Tree size. For example we can store relative coordinates with dynamic size of MBR (VRMBR), instead of absolute coordinates with fixed sized MBR. There is some evidences, that this can sufficiently reduce size. http://link.springer.com/chapter/10.1007/11427865_13
Sounds promising. Did you examine how this technique can fit into GiST? In current GiST interface methods don't have access to parent entries.
