I think it would be nice to add a unit test with the FG enabled so that we can assert that is part exists in the script. WDYT?

Yep, I think it's a good point. I will fix it.

CHANGE DESCRIPTION
Problem:
Excessive log generation from the replication-cert-copy container within the Postgres database pod. The container checks available disk space, and if the free volume is less than 75%, it triggers a Kubernetes API call to update the pod annotation with a suggested volume size (e.g., suggested-pgdata-pvc-size: 15345Mi).
Cause:
Short explanation of the root cause of the issue if applicable.
Solution:
Avoid updating the pod annotation unless AutoGrowVolumes is enabled.
