Обсуждение: Interface of the R-tree in order to work with postgresql

Hi everybody!
I'm Jorge from Peru -> South America
I'm new in the list, and this is my first post:

I want to know how can I add a new spatial access method into 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 for me 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 me
thanks in advance
regards

Developing a new index access method is hardly a novice-level task.
Are you sure you need to do that?  Perhaps you can accomplish what
you want by making a new datatype and interfacing it to GiST indexes.
That's still a pretty large chunk to bite off, but there are examples
available --- look into the contrib/ directory to find existing add-on
datatypes that have GiST indexing capability.  The documentation for
this area is weak.  Be prepared to read source code ...

Jorge, you may want to also check out PostGIS which specially enables postgres server.
