I have created a doc patch (attached) to document a clean way to take a
backup of the standby. This can be used for pitr, and to create
additional slaves, so I do think this will be used more during 9.0. You
can see the output here:

The actual list of steps only appeared in 9.0 so I suggest this only be
applied to HEAD and 9.0.X.
