Alexander Kukushkin 08865512f8 Differentiate between connection address and listen address 
For example you can listen on 0.0.0.0 but provide service on some
didicated ip. This should cover all possible use-cases when you are
running behind firewall, load balancer or inside for example docker.

Alexander Kukushkin 281b0b8455 Bugfix in has_lock: sometimes leader can be undefined 2015-05-12 11:07:52 +02:00
Alexander Kukushkin 9dcbc75fd2 Bugfix. It wasn't possible to start the old cluster if all its members were shutdown. 
Basically this is rollback to the original decision tree with the small exception:
1 - If leader is defined and it's not me - then slave would be started immidiately
with the correct recovery conf.
2 - If leader is defined in and it's my host, then it will start instance in
readonly (but without primary_conninfo in recovery.conf)
3 - And the third case - if the leader is not defined - it also will start
instance in readonly, without primary_conninfo.
After performing 2 or 3 it will perform usual decision tree.

Alexander Kukushkin be7677a1b8 Bugfix, hostname and address are not keys of dict but properties of Member object 2015-05-12 09:08:45 +02:00
Alexander Kukushkin e2faf641d5 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.
