I don't like that one much.

I agree.  Since pause_at_recovery_target is ignored when
hot_standby=off, I think it would be consistent to treat the case
where hot_standby=on but can't actually be initiated the same way -
just ignore the pause request and enter normal running.  However, I
don't have a super-strong feeling that that's the only sensible way to
go, so count me as +0.5 for that approach.
