Nothing like that has been reported before. We have heard of dump files
getting corrupted after they've been produced --- the most common case
is newlines (\n) getting converted to carriage-return-line-feed (\r\n)
due to being copied onto a Windows machine. The COPY data format is
reasonably impervious to that, but I suppose it's possible that a second
conversion step might incorrectly change \r\n to \n\n.

If you're certain that nothing is happening to the dump file after the
fact, then we'll need to see a self-contained test case.
