 - PostgreSQL is no longer automatically deployed due to the complexity of managing major version upgrades.
   You are strongly recommended to deploy a PostgreSQL server separately, for example:
-  - using a Helm chart such as [bitnami/postgresql](https://artifacthub.io/packages/helm/bitnami/postgresql)
   - using an operator such as
