Module to provide communication with a server in order to send new tasks and query them. pg-backup-api is a REST api that at the moment, is integrated with barman only, and can provide a communication interface in order to perform remote recoveries through background tasks. There are cases where instead of writing a new repmgr module of some feature that exists in backup tools already, like barman, pg-backup-api can provide that integration.
