hi !
thanks for writing!

In postgresql version 8.0.9 the rtree_gist implementation is located at
contrib/rtree_gist ready for compilation and then ready for loading it into
a database, I want to know where can I find this rtree_gist implementation
in versions 8.1.x

regards
jorge

You don't need to find it, it's built in.  Just create an index.

[HACKERS] Interface of the R-tree in order to work with postgresql

[jorge alberto]

Hi everybody!I'm Jorge from Peru South America, and this is my first postI want to know how can I add a new spatial access method into the postgresql (I'm doing research on spatial access methods( reading a lot of papers and programming a lot too ) but also I want to know how can I add my new data structure( if someday i get it, of course =) ) in the postgresql, I mean where can i find the .h that describes the 
interface that a spatial access method, like the R-tree, must have in order to work with postgresql.I
think that to understand how postgresql works with spatial
access methods, like the R-tree, I need to find a .h or .c to begin
reading the code, so can you tell me where to start?I hope you can help meregards Jorge
