ordinaryusers would be less interested in this LSN information than other ones like the number of buffers written.
Actually, there's no strong reason to put LSN info at the beginning of
the message except that LSN/REDO LSN next to the
checkpoint/restartpoint complete would make the users understand the
LSN and REDO LSN belong to the checkpoint/restartpoint. Since this
wasn't a strong reason, I agree to keep it at the end.
