Standby accepts recovery_target_timeline setting? - Mailing list pgsql-hackers

While testing against PG12 I noticed the documentation states that
recovery targets are not valid when standby.signal is present.

But surely the exception is recovery_target_timeline?  My testing
confirms that this works just as in prior versions with standy_mode=on.

Documentation patch is attached.
