DCAE postgres set is based on Crunchy Data Statefulset Helm Example.
It provides a statefulSet of two postgres replicas.
Remaining work: tweak services and PVs. Adjust the chart to
  DCAE needs.

+  # We usually recommend not to specify default resources and to leave this as a conscious

+  # Example:
+  # Configure resource requests and limits
