None of these points are really for or against either approach. In any
case, we would ship with all the required components, so no need to
install 3rd party software. The recovery related options would come from
recovery.conf in both models, although that could be changed if we
wanted to.
Not sure what easier to control (iii) means, although admittedly it's a
bit tricky to make it walreceiver behave correctly as a subprocess of
the startup process, making sure it responds to shutdown requests etc.
