Hey!
Not a big problem of course but currently when you do "pip install patroni" you still need to go to Github and save a copy of for https://github.com/zalando/patroni/blob/master/postgres0.yml to get started. I know there are env variables but there are quite some to remember. So would be very convenient if running something like "patroni --initconf postgres0.yml" would fill the postgres0.yml

The current repmgrd fencing technique (repmgrd invoking the child_nodes_disconnect_command) has 2 problems:

1. It only works when repmgrd is running and failover=automatic
2. It doesn't work if a failover happens when the node where the old primary was running is down at the time of the failover

The repmgrd documentation states (https://repmgr.org/docs/5.0/repmgrd-primary-child-disconnection

I want to call External Scripts after swichover/failover the new master and all slaves active . but the "failover-post-scripts" called after the new leader has been setup. can I do this ? how do it ?

Patroni supports defining some of the configuration parameters by setting the system environment variables. We should check existing environment variables (e.g. {{ ansible_env.SOME_VARIABLE }}) before tweaking the Patroni configuration file because those variables always take precedence over the ones set in the Patroni configuration fil
