Interesting problem, in practice you've got to transfer the file to the
server over the network anyway, so if the libpq copy gets fast enough it
would seem more efficient overall to use libpq copy.
On the other side, Oracle retains a true server side copy in addition to an
"external table" which maps to a file. This implies an audience for server
side copy functionality.
