We have linux host server and use docker container in it for hosting of postgresql 12 version database. Its postgresql.conf file ownership was postgres:postgres in container server and it was working fine.
Recently I did a timezone parameter change in the postgresql.conf file and then did pg_reload_conf() from pgadmin. Now, postgresql.conf file group ownership has changed automatically to some numeric number which is not available in /etc/group too. However, file ownership is postgres only and db is working.
I can do "chgrp postgres postgresql.conf" online but as it is a containerized database it may be sensitive to such changes so I want to be sure that this change would not adversely impact the container.
Please let me know if someone encountered such an issue and solution to it.
