This patch added this documentation text:
+ Replies are only sent when WAL is written to disk, so setting
+ <varname>fsync</> to <literal>off</> on the standby will significantly
+ reduce performance of synchronous replication and should be avoided.
Should we also issue a warning message in the server logs for the use of
fsync=off on the standby?
