Sorry, I was dim because of maybe catching a cold:p
On second thought. everything works fine if the first segment of the
new timeline is archived in this case. So the problem here is whether
recovery should wait for a known new timline when no segment on the
new timeline is available yet. As you say, I think it is sensible
that recovery waits at the divergence LSN for the first segment on the
new timeline before proceeding on the same timeline.
regards.
