How to set the TimescaleDB versions in the instance deployment manifest.yaml?

I use the helm for installing zalando operator. So, I use manifest.yaml for installing my postgres instances.

In my manifest.yaml i install and use the timescaleDB extension like that

apiVersion: "acid.zalan.do/v1"
kind: postgresql
metadata:
  name: acid-minimal-cluster
spec:
  teamId: "acid"
  volume:
    size: 1Gi
  numberOfInstances: 2
  users:
    zalando:  # database owner
    - superuser
    - createdb
    foo_user: []  # role for application foo
  databases:
    foo: zalando  # dbname: owner
  preparedDatabases:
    install:
      extensions:
        timescaledb: public
  timescaledb:
    version: 2.10.0
    
  postgresql:
    version: "15"
    parameters:
      shared_preload_libraries: timescaledb

I know that the Zalando image takes several versions of timescale DB.

However, I can not to set the version in the manifest.yaml. How to do?

It is possible to use a configMap by specifying the versions, but I would like to avoid making it complicated.

Start by reviewing the instance deployment manifest.yaml and the Helm configuration, including the configMap approach mentioned in the report. Determine whether TimescaleDB versions can be selected in the manifest; done means documenting the supported configuration or clarifying that the configMap is required.
