As Tom mentioned already, the binary protocol is actually pretty well
defined, and it's in network-byte-order, aka, big-endian. The only
issue that I can think of off-hand that you need to know about the
server is if it's using 64-bit integers for date-times or if it's using
float. That's a simple check to do, however, specifically with:

show integer_datetimes;

It's also alot cheaper to do the necessary byte-flipping to go from
whatever-endian to network-byte-order than to do the whole printf/atoi
conversion. Handling timestamps takes a bit more magic but you can just
pull the appropriate code/#defines from the server backend, but I don't
think that's even an issue for this particular set.

What does your test harness currently look like, and what would you like
to see to test the binary-format COPY? I'd be happy to write up the
code necessary to implement binary-format COPY for this.

Thanks,

Stephen
