The patch at the moment was enforcing just the setting at startup (which is more than enough for a Kubernetes operator given that Postgres runs in the container). I had done some experiments enabling the change in the configuration file, but wasn't sure in which `config_group` to place the 'enable_alter_system` GUC, based on the src/include/utils/guc_tables.h.
