The problem with COPY FROM is that it hard-wires a decision that there
is one and only one possible result format, which I think we pretty
much proved already is the wrong thing. I'm not thrilled with "RETURNING
ARRAY" either, but we need to leave ourselves wiggle room to have more
than one result format from the same source file.
