CNPG integration

[stevefan1999-personal]

I would love to see if we can use CNPG to offload automatic database and WAL backup to S3

Also interested in this, as this is also available as a microk8s addon.

This could go hand in hand with a traefik proxy, since they also support tcp ingresses for postgres (which solves the current issue of CNPG certificates)

I'm totally in for CNPG, though I have limited experience with it.

TCP ingress for PostgreSQL should be managed by additional resources, possibly in Kubero, but it's not implemented yet.
