Ah, I see it.
What happened there is I accidentally included it when I split my
patches apart. It's required in the "stream WAL in parallel to the
base backup to decrease requirements on wal_keep_segmtents". But that
patch was postponed since there were still bugs in it, and it wasn't
entirely feature-complete, and we were pretty far past feature-freeze.
So it's not needed in 9.1. I'll rip it out and move it over to the
patch once it's ready to go for 9.2.
