Searching ... it is possible.  However, the way to do so is actually
scattered among 5 different doc pages.  I'm not sure that I'm up for the
surgery required to make this make sense to users ... anybody else have
the energy/time?

The relevant pages in the docs are these:

http://www.postgresql.org/docs/9.4/static/standby-settings.html
http://www.postgresql.org/docs/9.4/static/functions-admin.html#FUNCTIONS-REPLICATION
http://www.postgresql.org/docs/9.4/static/logicaldecoding-explanation.html#AEN66111
http://www.postgresql.org/docs/9.4/static/warm-standby.html#STREAMING-REPLICATION

... otherwise, I'll just write a blog or postgresguide or something.
