But isn't that an argument *for* having support for the binary format in
libpq in a form similar to what this patch offers? Then at least you'd
be safe as long as your libpq-version is >= your server version.
Currently, there seems to be no safe way to use the binary format,
despite it's benefits for moving around large amounts of data.
