unrecognized configuration parameter "allow_alter_system" in file "/var/lib/postgresql/data/pgdata/custom.conf"

Hi,

I am using following versions.

Cloudnative-PG operator: 1.24.0
Postgis: postgis/postgis:16-3.4
Postgis Release: 64
Kubernetes: 1.30.3

I have build my own docker image using Dockerfile, .versions.json and requirement.txt. I did not applied any updates to these files. I am receiving following error message when I try to create postgres cluster and cluster node goes in complete status.

unrecognized configuration parameter "allow_alter_system" in file "/var/lib/postgresql/data/pgdata/custom.conf"

let me know if you need any additional detail.

thanks,
Laukik

Hi, allow_alter_system is a GUC that's only present since v17. You should remove it from your PG configuration
