Maybe there is another way to read those, but it looks to me like
David says you
can trivially swap the roles of the nodes using the '-r' switch (and
he provides a
link to the documentation), and you say that you can't trivially swap
the roles of
the nodes.
The -r switch temporarily reverses the direction of data flow from
the secondary to the primary to sync up an outdated primary. After
that, the data flow reverts back to primary to secondary. Reversing
the roles requires many more steps (and time)...
