Describe the issue

I get the following fatal error in the logs when upgrading from helm chart 0.5.16 to 0.5.17:

postgresql 12:51:27.33 INFO  ==> ** PostgreSQL setup finished! **
postgresql 12:51:27.43 INFO  ==> ** Starting PostgreSQL **

I already tried

• I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

• Install helm chart 0.5.16 with persistency.

I've solved the issue for now by adding the following to the value file:

postgresql:
  image:
    tag: "16.4.0-debian-12-r9"

It would be really nice if there would be warnings and upgrade instructions as long as the helm chart doesn't handle the upgrades automatically
