No difference at all ! It's just another implemetation of R-Tree.

unfortunately not ! Current postgres code has nothing connected with
GiST and this is a problem ! How to test interface code without
having two sides ? I understand we don't want to have another reason
for complaints about non-working regression test. I never got
regression test passed 100% on my Linux box with almost all versions
of PostgreSQL but I could live with that. What's wrong with
warning message if GiST test not passed ?

I'm interesting to test performance of built-in R-Tree and R-Tree + GiST.
