Environment: PostgreSQL 13.x Docker container.

I took a pg_basebackup and have configured PostgreSQL 13.x with wal_archive=on. And it is working as expected.

I see that it is recommended to take pg_basebackup periodically. How can I rotate the base_backups weekly or daily?

Example: If new pg_basebackup is running every Saturday night, Should we consider stopping/pausing wal_archiving for that duration?

#Locations:
pg_basebackup : /db-backup/basebackup
archive_command: /db-backup/wal_files

So want to move archive db-backup every Saturday.

mv /db-backup /db-backup-old

While performing these Should I pause the wal_archiving process? As per docs we can stop/pause it by setting 24.3.1. Setting up WAL archiving

archive_command = ''

Is this the right approach? If so, should we reload the configuration OR any way we can update this configuration on-the-fly? Note: using Postgres-docker container.

What I am trying to achieve is:

If some data is getting written on DB during DB backup rotation, either it should be in new basebackup OR new wal-files directory.

Please correct me if these confusions are irrelevant.
