Re: Upgrading postgres to 10 running with patroni

After upgrading my patroni to 1.3.6 I am not seeing any exception. But on
trying to start patroini I am seeing logs like below

ubuntu(at)vrni-platform:/var/log/postgresql$ patroni /etc/patroni/patroni.yml
2017-11-16 19:19:38,036 INFO: Connecting to localhost:2181
2017-11-16 19:19:38,040 INFO: Zookeeper connection established, state: CONNECTED
2017-11-16 19:19:38,053 INFO: Lock owner: None; I am postgresql0
2017-11-16 19:19:38,058 INFO: waiting for leader to bootstrap
2017-11-16 19:19:38,061 INFO: Lock owner: None; I am postgresql0
2017-11-16 19:19:38,061 INFO: waiting for leader to bootstrap

Also postgres is not running

psql -U postgres -d vnera -p 5432 -h 127.0.0.1
psql: could not connect to server: Connection refused
Is the server running on host "127.0.0.1" and accepting
TCP/IP connections on port 5432?

Can someone let me know how can I get around this? Do I have to make
any changes in `patroni.yml` after upgrading to 1.3.6 ?
