To Reproduce
Steps to reproduce the behavior:

1. install addon

helm upgrade --install --namespace kb-system kb-addon-apecloud-postgresql kb-addons/apecloud-postgresql --version 1.0.0-alpha.0 --set image.registry=apecloud-registry.cn-zhangjiakou.cr.aliyuncs.com --set images.registry=apecloud-registry.cn-zhangjiakou.cr.aliyuncs.com

2. create cluster

kubectl apply -f -<<EOF
apiVersion: apps.kubeblocks.io/v1
kind: Cluster
metadata:
  name: apepg-vhhhwp
  namespace: default

spec:
