Doesn't seem like "starts recovery" is the point at which you can start
letting clients into the DB. What you want is to reach a point at which
you're sure that the DB is internally consistent, though perhaps not
fully synced with the master. In a PITR recovery scenario this would
correspond to reaching the minimum safe stop point. In true crash
recovery I don't think you can let people in till you're done.
