Hmm. I might be misremembering, but I think that it's the archiver
process that is in charge of deleting those files, so that this behavior
doesn't seem surprising.
I don't think anybody's thought very hard about how to clean up if
archiving had been running and then you turn it off with not everything
having been archived.
Manual cleanup shouldn't be very hard, fortunately. Run pg_controldata
to see where the last checkpoint is, and delete WAL files whose names
indicate they are before that (but not the one including the checkpoint!).
If you don't intend to do archiving any more, you can just flush all the
.ready files (and .done if any) without much thought.
