Just because the timeline is old doesn't mean we want to destroy it.
Afterall, the reason for having timelines in the first place is to
preserve, not to destroy.

It sounds like someone removed the old timeline's log files from
pg_xlog, but did not remove the corresponding .ready files from
pg_xlog/archive_status.

If the old timeline's files are truly lost, then you will have to
carefully remove those corresponding .ready files.
