The reason why backup manifests are sent at the end of a base backup is that they include the start and stop positions of the backup (see caller of AddWALInfoToBackupManifest() in perform_base_backup()). Once this is done, an extra CopyOutResponse message is indeed sent within SendBackupManifest() in backup_manifest.c. So confirmed. -- Michael
