Right; I really dislike the idea of having two separate code paths for
COPY. When you say this approach is "temporary", are you suggesting that
you intend to reimplement your changes as improvements/replacements of
the existing COPY code path rather than as a parallel code path?

I'm definitely not keen to see a new "LOAD DATA" command.

In what way would the performance improvements to COPY be backward
incompatible with the existing COPY behaviour?
