_loki1.pyrocufflink.blue_ replaces _loki0.pyrocufflink.blue_. The
former runs Fedora Linux and is managed by Ansible, while the latter ran
Fedora CoreOS and was managed by Ignition and _cfg_.
This script captures the steps taken to migrate from the PostgreSQL
server in the Kubernetes cluster, managed by _postgres operator_, to the
dedicated server on _db0.pyrocufflink.blue_. The data were restored
from the backups created by _wal-e_, and then the new server was
promoted to primary. Finally, I cleaned up the roles and databases that
are no longer needed.
