A lot. A whole lot, more than what most people have in production with
more than that. You are forgetting a very large segment of the

Why don't we just have 3 default config files:
2GB memory
4GB memory
8GB memory
Have initdb detect how much memory is available on the machine in TOTAL
and pick the most appropriate.
