I run a two service cluster in the home lab for fun. I use PVC mapped to a NFS share for the actual data so you could always run a local postgres binary against it. In a production environment I would map these to local disk partitions like you would normally do for a db.

The upgrade process is actually quite nice when it works but it is "another" thing to learn and troubleshoot.

I think of CRDs as a troubleshooting flowchart that someone with more experience than me has put together. When it's right it's great and when it's wrong it makes trouble shooting harder. That is until you remember that the whole point of k8s is ephemeral containers. When one breaks just delete it and let pgcluster CRD resync the data.
