> We have seen cases recently where we have wal from 2018 timestamp in our
> recovered replication queue. We came across this un replicated wal while
> debugging something else. We need to have metrics for the oldest wal in the
> replication queue and have alerts if it exceeds some threshold. Clearly 2
> years old wal is not desirable.
