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. -- Michael
