I am not able to startup Postgres. Installed version 1.16. I am getting the following error. Any thoughts?

Hi @joubertb,

it looks like you're using an outdated K8S version (1.20.15), which does not support the stable Cronjob API. For this to work, you will need to upgrade your cluster, to a more recent version.

On a different note, I believe that it would be advisable to update your cluster anyway, in order to ensure that the version you're running is properly patched. For more details, see the documentation: https://kubernetes.io/releases/.

I hope this helps.

Cheers
Ben
