If it is a newline-conversion problem, compressed pg_dump archives would
be just as subject to corruption as your binary COPY file is. I'd say
the hint is to be more careful about how you do the cross-machine file
transfers. I suspect what is really happening is you're not always
doing that the same way, and that some of the methods allow a newline
conversion to happen to the file while others don't.
