Start slave with the correct recovery.conf on governor start
...
Also governor is able to pick up already running master and slave
instances without restarting them.
In case is you have a lock and postgres is not running behaviour remains
the same: it will start master in read only mode and then promote if it
still has the lock.

update it.

dempote and follow_the_leader have the same functionality
...
Now methods supporting the case when leader is not defined. There would
be no primary_conninfo in recovery.conf. I like it more comparing to
postgres://169.0.0.1:5432
