Peter,
I believe we're just copying Oracle's terminology. While that
terminology is not consistent, it is understood by the industry. Oracle
defined their Hot Standby to have both asynchronous and synchronous modes:
http://www.oracle.com/technology/products/rdb/htdocs/dbms/hotstandby.html
The other industry term which would be understood would be "log-based
replication". Terms we invent would be less likely to be understood,
and users would not get excited about them.
Otherwise, I say we go with "simmering follower". ;-)
