During the execution of the "delete" command, the oldest start LSN is saved and used to determine what is the oldest WAL segment that needs to be kept for the existing backups. Like pg_archivecleanup, the implemented logic ignores the timeline part of the WAL segment name, ensuring that a segment from a parent timeline will not be removed prematurely. This logic could be made more complicated regarding this matter, but in order to take backups from a node on a given timeline this is far enough. |
