In HEAD, when the standby is promoted, recovery requests the checkpoint

of this checkpoint looks odd as follows:

I think something like the following is better.

     LOG:  checkpoint starting: end-of-recovery

In 9.2 or before, "end-of-recovery" part is logged. Even if we changed the
behavior of end-of-recovery checkpoint, I think that it's more intuitive to
label it as "end-of-recovery". Thought?

The checkpoint isn't an "end-of-recovery" checkpoint, its just the
first checkpoint after the end of recovery. I don't think it should
say "end-of-recovery".


The problem is that we've now changed the code to trigger a checkpoint
in a place that wasn't part of the original design, so the checkpoint
called at that point isn't supplied with a reason and so has nothing
to print.

It would be possible to redesign this with a special new reason, or we
could just use "time" as the reason, or we could just leave it.

Do nothing is easy, though so are the others, so we can choose
anything we want. What do we want it to say?

I'm not sure. Perhaps we should print "(no flags)", so that it wouldn't look like there's something missing in the log message.
