as I said before, when the checkpoint timeout goes off, a partially written WAL log will be archived. this file is still the full size, its not 'short', its just empty.

too big of a file will mean a LOT Of waste data is being copied and archived.

what is your checkpoint_timeout ? how many WAL files per that timeout interval are you generating now? (like, if the timeout is 5 minutes, and you're generating 36 files per hour, that would be about 3 WAL files per timeout interval...)
