Important

The Postgres Operator version you install must be 1.9.0 or later, as all versions up through 1.8.2 use the PodDisruptionBudget policy/v1beta1 Kubernetes API, which is no longer served as of Kubernetes 1.25. This being the case, various MSR features may not function properly if a Postgres Operator prior to 1.9.0 is installed alongside MSR on Kubernetes 1.25 or later.
