Question in topic:

"How can I set up Postgres to use given amount of RAM?"

I have now laptop with 8GB of RAM, i can see Linux uses no more than 2-3GB.

So my question is how to FORCE PostgreSQL

use let's say 2-4Ghow to B of RAM for caching tables I run queries on?

As I can see disk actity running queries.

The closest thing I can think of is effective_cache_size:
