Rohit

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.

That sounds pretty exotic, I can't imagine what good the index will do if it doesn't contain tuple IDs.

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?

See user manual, and the examples in the server code and contrib.
