Well, I suppose only performance will tell. Copying a buffer is sure to
be faster than invoking all of the type input/output functions, or even
send/recv, so perhaps it's not a huge penalty.

My disagreement with the row-by-row approach is more semantics than
performance. COPY translates records to bytes and vice-versa, and your
original patch maintains those semantics.
