Ah, you can tell I hadn't gotten to the bottom of the patch yet ;-).
Still, that's not a 100% solution because of the cases where we use
reconnections to change user IDs --- the required password would
(usually) vary.  It might be sufficient to forbid that case with
parallel restore, though; I think it's mostly a legacy thing anyway.

Yeah, found that too.
