Hi, 
Thanks for reply.
I actually want to make some changes in all operations on index like insert, update, delete.
for example, i want store a new customized value for every key inserted in b tree instead of storing Tuple Id as value.

Can you also pls explain me more about appoach to follow to use my algorithm as GiST opclass. I dont have much knowledge abt this also?

Regards,
Rohit Goyal

Hi All,

I want to implement and test my indexing approach.
I would like to know which are the main files to look for b tree indexing
scheme modification.

It would be great, if can share some helpful links which are needed to
understand how to modify and test an indexing scheme in postgresql.

You didn't give any details on what kind of changes you want to make, so hard to tell. The code for the btree access method is in src/backend/access/nbtree. See the README in that directory for the gory details.

Also consider implementing your algorithm as a GiST opclass, instead of changing the internals.
