This post suggested a performance improvement to the initial copy might
appear in 1.2, by removing indexes and re-applying them.

>From reading RELEASE-1.2.0, I didn't see a mention to that effect. Is an
optimization like this in place?

If not, is the recommended practice to drop all the non-primary-key
indexes, and then re-apply them later?
