Actually, sorry, I lie, but not in a bad way.... Since COPY operates
row at a time (rather than a stream of bytes with arbitrary
boundaries) you could rely on being passed each record one-at-a-time.
You don't have to understand the delimiter. So you could even make a
bytea[][] that even contains the binary output, the first dimension
being row number, the second being the bytes themselves. The header
would pose an interesting problem, though.
