If no reply is returned from the standby in replication_timeout, the master thinks that the connected standby is inactive, and terminates the replication connection. This is useful for the master to detect a standby crash or network outage. > Basically I wish my synchronous write transaction to not wait indefinitely > when the synchronous standby servers are not available.

You would need to implement something like the monitor daemon which disable synchronous replication when it detects a standby crash or network outage.
