Yes, that TIP is very long obsolete.   However, kill -9 is still not
the *preferred* way to shut down the postmaster ;-).  You don't get
a checkpoint, and in some cases the shared memory block may not get
recycled when you try to restart the postmaster, leading to serious
memory wastage.

I'd suggest we just remove that TIP from the set of possible messages...
