This didn't actually work: COPY would fail to flush the right files, and instead would try to flush a non-existing file, causing the whole transaction to fail. Cope by raising an error as soon as the command is sent instead, to avoid a nasty later surprise. Of course, it would be much better to make it work, but we don't have a patch for that yet, and we don't know if we'll want to backpatch one when we do.
