Feature: Automatic Configuration of HugePages

Tasks:

    • Link to the current setting: system.yml#L56.

  2. Pre-check:

    • Add a pre-check for the huge_pages parameter in PostgreSQL.
    • If the huge_pages parameter is set to on, verify that the vm.nr_hugepages kernel parameter is configured with a sufficient value.

I have just enabled this in my cluster with 1GB pages, so I could contribute to this feature.

@rcknr Thank you, I'm already working on it, I'll publish a PR soon and I'll be glad if you take part in the testing.
