I'm just comparing your idea (i.e., set synchronous_standbys on
each possible master) with my idea (i.e., set replication_mode on
each standby). Though your idea has the advantage described in the
following post, it seems to make the setup of the standbys more
complicated, as I described. So I'm trying to generate better idea.
