COPY.  If you're loading a TB, if you're smart it's going onto the server
itself if it all possible and loading directly from there.  Would probably
get a closer comparision against psql \copy, but recognize you're always
going to be compared against the best server-side copy method available.

Wouldn't have time myself for at least a month (probably not until after
the East convention) so don't go making commits on my behalf.

There are way too many data massaging cases I never expect the backend
will handle that pgloader does a great job of right now, and I think there
will always be a niche for a tool like this.
