I want to deploy a highly available PostgreSQL in a K8S cluster. The persistent volumes are leveraging a Ceph cluster that is already configured with replication.

So my only requirement is to achieve replication at service level, not at data level.

I had a look over stolon , patroni and the "official" helm chart but as far as I can tell, none of them are supporting my scenario.

Are there any OSS solutions implementing my use case ?
