The PostgreSQL buffer is called shared_buffer which is the most effective tunable parameter for most operating systems. This parameter sets how much dedicated memory will be used by PostgreSQL for cache. It’s low because certain machines and operating systems do not support higher values. wal_buffers.

The more indexes, the more the requirement of memory for effective caching. If we don’t increase the available memory, this starts hurting the entire performance of the system. Indexes need more cache than tables Due to random writes and reads, indexes need more pages to be in the cache.
