Re: [BUG] Checkpointer on hot standby runs without looking checkpoint_segments

Nevertheless, checkpoints will be triggered by checkpoint_timeout and
run at the maybe higher speed governed by checkpoint_segments. This is
undesirable behavior from such a point of view.

But I think referring checkpoint_segment on such case should be
inhibited, and I suppose it is possible using StandbyMode in
IsCheckpointOnSchedule(), I suppose.

I will correct the patch later.
