RemoveOldXlogFiles() would discard any of those .deleted files because
they don't match a legal WAL segment name, so checkpoints are not able
to work on them even in the future. I would avoid meddling with
anything that a backend may finish to touch while running, but that
should not really matter here as they are just never chosen for
deletion. Piling up those files is not a good thing, so while you
still need to figure out what's causing those files to remain around
on your side, perhaps we should improve the situation in the backend
itself.
