Thanks Atri!
Do you know why PostgreSQL store the indexes in memory per process and not in the shared memory?
Is there a way to prevent it store the indexes data per process, and force it storing it in the shared memory?

Well, I am not too sure, but indexes always take up more space, so if your backend has a lot of indexes, it will cause
theprocess to consume more memory.
Indexes should be used with care, as too many indexes can cause a memory overhead,which can cause performance
degradations.
