This new index structure is based on the R-tree. I changed some of the code of the R-tree as provifded with Postgres. My question is: What do I have to do to use this new index structure with Postgres? What relations need to know about this new index structure ? What I would like to have is a stepwise procedure for this problem. Greetings ____________________ \ / . _ _ _ _ | \/ ( ( \ (_ (-' ( \ | P.S. I've reported a problem about defining an R-tree index after all the tuples are appended. This seems not to work, while definig first the index and append the tuples afterwards does work. I want to be able to copy all the tuples to a relation because it is much faster than appneding. Since my masters thesis is depending on this, would you please look at this problem soon.
