The problem with that is that it duplicates effort: in many cases
(especially COPY IN) the data's already been validated. I'm not sure
how to fix that, but I think you'll get some push-back if you double
the encoding verification work in COPY for nothing.
Given that we are moving away from backslash-enabled literals, I'm
not as convinced as some that this must be fixed...
