Shutdown of Kubernetes Cluster - Not able to restore the pg-cluster and database

[supermario18b]

Hi everyone,
I'm testing Kubernetes on microk8s on a 3 nodes Cluster. I've created with the zalando-operator a 3 replicas postgres-cluster with one database on it.
The 3 nodes are Virtualbox-Vms. I shutdown the VMs everyday and when I start them again, I find that the PG-Cluster-Pods are in status "Terminating". If I force the deletion of the pods, other pods are created but postgres doens't run on these pods and the database is gone.

Is it possible to get back the database (working) after a complete shutdown of the kubernetes cluster?

Thanks in advance,
