This chart is a wrapper for the [Zalando postgres operator](https://github.com/zalando/postgres-operator) to create
a high available Postgres cluster using nodes local storage.

Features added by this wrapper:
- creates an storage class using local storage in the nodes specified in `persistentVolumes.replicaNodes`. These replicas survive
  a tear-down and tear-up of the cluster.
- (optional) does sql dumps to an existing PVC with K8S cronjobs. The Operator only supports backups to cloud, not NFS PVC for example.
- Define the password for the DB so that it can be used accross tear-down and tear-up of the cluster.
