It's not strictly a "tuple" until it's been loaded.

Not so with COPY.  The record separator is hard-coded
to be a newline: the field separator can be set at
runtime, but the record separator cannot.  That would
be a nice feature to have, though.

Various people have wished for an import application
with more intelligence than COPY now has.  No doubt
much of this could be achieved simply by building
extra features into COPY.

With about three more years of study, I might have the
competency to attempt that myself.  In the meantime,
is anyone else volunteering? :-)
