No, slaves cannot do synchronous replication. I am just telling that
once you are sure that a sync state has been achieved on the master,
you have the guarantee that data gets synchronously replicated on the
standbys as long as you do *not* change synchronous_standby_names. So
there is no actual need to know what's the state of the master during
a failover to a sync standby.
