(I'm going to make a note to test this with loading large vectors :) 
I've modified the text to reflect this. Please see the new language 
upthread.

I don't agree with this. I think we want to push COPY as a developer 
feature - I see a lot of people not utilizing COPY appropriate when it 
would really benefit the performance of their app, and I think 
emphasizing it as the way to do bulk loads (while touting that it's even 
faster!) will help make it more apparent.

Thanks.

Adjusted.

I have to check if these have deep links or not, but I was planning to 
make another pass once the copy (no pun intended) is closer to 
finalized, so I don't have to constantly edit markdown.
