Unable to create timescaledb_toolkit extension using helm chart

Hi guys, recently i try to deploy timescaledb using helm chart on k8s, but unfortunely i can't find the timescaledb_toolkit extension after installed

• Which image of the operator are you using?
• ghcr.io/zalando/postgres-operator:v1.14.0
• Where do you run it - cloud or metal? Kubernetes or OpenShift? [AWS K8s | GCP ... | Bare Metal K8s]
• Helm Chart Kubernetes
• Are you running Postgres Operator in production? [yes | no]
• yes
• Type of issue? [Bug report, question, feature request, etc.]
• Bug

apiVersion: "acid.zalan.do/v1"
kind: postgresql

      nodeSelectorTerms:
        - matchExpressions:
            - key: "application"
              operator: In
              values:
                - dependency
  tolerations:
    - key: "application"
      operator: "Equal"
      value: "dependency"
      effect: "NoSchedule"

Begin with the Helm chart and the PostgreSQL manifest's preparedDatabases.extensions block, using the stated operator image and PostgreSQL 16 configuration. Reproduce the deployment and verify whether timescaledb_toolkit becomes available; done means the extension is present in the prepared database or the relevant chart or image limitation is documented.
