-* Register each cluster in puppet's
- {{{puppet:modules/postgres/manifests/backup_source.pp}}}.
- This takes care of adding the replication user to pgpass on the backup servers,
- and the firewall rule and adds the cluster to {{{make-base-backups}}}.
- (The module can also create the postgres role and modify the hba file, but we
- do not do this when we don't configure the entire cluster via puppet.)
-* Historically, we also have clusters hardcoded in
- {{{puppet:modules/postgres/templates/backup_server/postgres-make-base-backups.erb}}}.
