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...)
