We did this (from the 9.6 release notes):
Allow synchronous replication to support multiple simultaneous
synchronous standby servers, not just one (Masahiko Sawada,
Beena Emerson, Michael Paquier, Fujii Masao, Kyotaro Horiguchi)
The number of standby servers that must acknowledge a commit
before it is considered complete is now configurable as part of
the synchronous_standby_names parameter.
You can see the details here, e.g. "3 (s1, s2, s3, s4)"
