[~sershe], FYI.

And ping [~zghaobac], I think we could add a replication peer on our staging cluster to see if there are problems.

> This is a missing part in our ITBLL. We can config a dummy replication endpoint which replicates nothing but only reads and verifies that all the wal files are readable and the entries are all fine.
> With this I think it will be much easier to catch the problem in the parent issue.
