Whelp, I'm an idiot. I can't account for how I did it, but I can only
assume I didn't export my ports in the tests properly. I ran
everything again and there's a marked difference between 9.3 and 9.4.
The parallel copy times still inflate, but only from 1.4s to 2.5s at 4
procs. Though it gets a bit dicey after that.



Do the times still inflate in the same way if you perform the COPY before adding the indexes to the table?
