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?
