apiVersion: v1
kind: Namespace
metadata:
   name: postgres-namespace
   ownerReferences:
    - apiVersion: v1
      controller: true
      blockOwnerDeletion: true

ownerRefrences

when we delete the database called postgres, this should result in the automatic garbage collection of the namespace “postgres-namespace”.

kubectl get database postgres -oyaml | grep uid

通过ownerRefrence去关联不同scope之间的resouce，但始终都有一个uid来关联
