@cmoulliard Thanks for reporting this. We will investigate.

@cmoulliard The problem is with the API version used for the statefulset on the chart that the plan 10-8-0 uses:
https://github.com/helm/charts/blob/637a0bd43ded93bcb6c7ee497c2f0610fbf95a0e/stable/postgresql/templates/statefulset.yaml#L1

It's quite old. Can you go for PG 11? Another alternative (not so trivial) is to provide your own Helm registry with the chart patched to use the new API version.
