No, because COPY BINARY will emit its own sort of wrappers around the
data.

What I don't like about Andrew's proposal is that it seems rather
limited.  Why bytea in particular?  Text chunks could probably also use
a direct output method.  And what about input?

Could we do anything with a notion of a COPY RAW mode, that would dump
or read the data without any header, column, or row separators?  On
input I suppose you'd have to restrict it to one column --- on output,
we could leave re-dividing the data to the user's ingenuity ...
