Well, the point of the "unexpected pageaddr" message is exactly that the
WAL location it found in the next file wasn't the expected next location
in sequence (which would have to be something larger than 0/66000000).
This indicates that the next file isn't really new WAL, but a segment
file that was recycled (by renaming it to a higher file number) but not
yet overwritten with new data.
