There is always transations to commit, I(barman) do pg_basebackup once a day, and recieve wal with pg_receivewal(standby slot). And everything is fine, i have all data on OLAP DB(restore 6 times in day)
(all WAL files playing correctly).

I don't see any reason to believe there's a bug here. That message
would only appear if at least one transaction commit or abort record was
replayed from WAL, and it's quite possible there wouldn't have been.
