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

I would try docker with --memory option. An alternative is to create a VM with the given amount of memory. If your laptop is memory starved, then creating a VM is probably not an option. Docker is much cheaper. Dockerfile is relatively simple to master and you can use Docker to run almost anything.

The closest thing I can think of is effective_cache_size: https://www.postgresql.org/docs/current/runtime-config-query.html#GUC-EFFECTIVE-CACHE-SIZE
