Should the text include a mention of synchronous vs. asynchronous? Or
does master-master imply synchronous?
It shouldn't. It is possible to have synchronous replication without it
being master<->master.

While the answer may have been a little dated, this still seems to be an
FAQ.
Was there a discussion on removing this? If so I'll go read that, but ISTM
this question should remain.
agreed, this definitly does fall under a "Very FAQ" kinda thing ...
pointers to the various methods that are currently in use, at a minimum,
would be good ...
Yep, big mistake my removing the replication FAQ item. I have re-added a
new one:
4.21) What replication solutions are available?
Though "replication" is a single term, there are two major replication
technologies. Multi-master replication allows read/write queries to be
sent to multiple replicated computers. Using this capability has a
serious performance impact. Pgcluster is the most popular such solution
available for PostgreSQL. Master-slave replication allows a single
master to receive read/write queries, with slaves able to accept only
read/SELECT queries. The most popular master-slave PostgreSQL
replication solution is Slony. There are also commercial and
hardware-based replication solutions available.
