Never thought about a trigger on a COPY before. I'll look into that and
see what the hit is.

I was kinda hoping there was the equivalent of \N for indicating the use
of a default value instead of a null value, but I accept that such a thing
might be too expensive for COPY's goal in life.

Maybe the best approach is to switch to a batched insert, which might be
fast enough for my needs.

Thanks for the suggestions!
