It's not going to be possible to fix that without enormously invasive
changes (affecting individual datatype I/O functions, for example).
And in general, fields approaching that size are going to give you
problems in all kinds of ways, not only COPY.
I think we should be satisfied if we can make COPY deal with the sum
of a line's fields exceeding 1GB.
