How can I check the load of the PostgreSQL container?
pgmetrics will not tell you anything about the load in your database and container. It is more about the details of the internal structure of the database. You can try the pgcenter tool. https://github.com/lesovsky/pgcenter

Homelab: Running Postgres on Kubernetes
My holiday project was doing another pass at my Homelab Kubernetes cluster, part of which involved switching to a proper operator to manage Postgres. Coincidentally, I setup cloudnative-pg (https://github.com/cloudnative-pg/cloudnative-pg) yesterday.

Kubernetes postgres backups
We already had backup and recovery using object storage, but we are working to support VolumeSnapshots taking care to properly shut down the instance first! This awesome PR is laying the foundation for it, it's adding a subcommand to our kubectl plugin to manually perform a backup using VolumeSnapshots and adding support for restoring a Cluster from it, next step will be adding it to the ScheduledBackup/Backup resources too!

Anyone using cloudnativePG operator knows if it's possible to save backups to a local dir or NFS?
I'll ask in their slack channel later. I've also opened a discussion regarding this on github if you are interesed. https://github.com/cloudnative-pg/cloudnative-pg/discussions/2030

What are you using to run Postgres?
This has a bunch of side-effects that break usual expectations around scheduling. For instance, cluster scale-down (for maintenance etc.) is blocked unless a specific taint has been added to each database pod. In addition, if the underlying node does fail, your cluster will be stuck in fail-over state until you manually delete the underlying pods. I think there are definitely other gotchas around this decision to use a custom controller but I have only tested this on GKE.

Can you create a Postgres Deployment with multiple replicas consuming to the same PV?
Another option would be https://github.com/cloudnative-pg/cloudnative-pg I got to see this talk at Kubecon last month that might be of use to you too -> https://www.youtube.com/watch?v=99uSJXkKpeI That talk is run in part by EDB, who are the company behind CloudNativePG, they are talking about their commercial offering, but the principle is the same.

How do people read CRDs?
Following another post on this sub, I was checking out the Github project and landed on this 2864 lined CRD https://github.com/cloudnative-pg/cloudnative-pg/blob/main/config/crd/bases/postgresql.cnpg.io_clusters.yaml. How are sane people reading these files?
