With master/standby-replica-slave, it is clear what multi-master is, and
what master/replica is.  If you start using active-active, is it
active/replica?  The full choices are:

	master
	primary
	active

and

	standby
	replica
	slave

Whatever terms we use, it would be nice to use the same term for the
multi-master as for master/replica.  Using active-active and
primary/replica just seems odd.  Multi-primary?  Seems odd since primary
suggests one, though multiple master seems odd too, i.e., more than one
master.  Multi-active seems the most logical, or active-active, but then
active-replica seems odd because it suggests the repica is not active,
i.e. does nothing.  Is no clear logical terminology possible?
