If someone wants to know how to host a database for the first time, I have a full chapter on PostgreSQL (and one on Redis) in my new book https://deploymentfromscratch.com/ https://deploymentfromscratch.com/. There is also a demo that sets up an independent database server (which you can treat as your own managed db). It's easier than you think if you stick to your distributions' packages. Just need to know how to 1, do auth right 2, enable SSL 3, run with SELinux 4, set a different location (for attached storage) 5, managed backups.
