Streaming Replication Across Kubernetes Postgres Clusters

A common need when running PostgreSQL in Kubernetes is to establish a standby database in a different Kubernetes cluster. In a typical configuration there is a shared storage that both Kubernetes clusters have access to. Using the pgBackRest tool, this can be S3 compatible, GCS, Azure, or NFS. You can create a standby from an initial backup from the shared storage. As WAL segments are archived, pgBackRest loads the segments to the shared storage.
