Minor changes to recovery pause behaviour.
Change location LOG message so it works each time we pause, not
just for final pause.
Ensure that we pause only if we are in Hot Standby and can connect
to allow us to run resume function. This change supercedes the
code to override parameter recoveryPauseAtTarget to false if not
attempting to enter Hot Standby, which is now removed.
