Обсуждение: Can we load all database objects in memory?

Deepak,

please don't cross-post the same question to 3 different lists.

The short answer is no, you cannot force PostgreSQL to load all
objects into memory.

However when you proper configure PostgreSQL most, if not all of your
data will be cached
by the OS and/or PostgreSQL shared memory system.

Increase effective_cache_size parameter.

An "effective_cache_size=11GB" should be more than enough.
