thanks for reply. :) Moreover, I am so confused about reading the nbtree
folder c files or the file which you gave.

For example, If I want to read how the data is inserted in B tree index.
Should I read your link or the btinsert(PG_FUNCTION_ARGS) in nbtree.c file
in nbtree folder.

In future, if i want to modify btree indexing approach, then which files to
look for.?
