Can someone let me know what I am doing wrong and how can I get around this error?

EDIT

I have made the changes to data_directory as suggested in an answer. But now I am getting the below error

I have made listen_addresses='*' in both the postgres.conf. But still getting the same issue.

Firstly Thank you for listing all the steps in your process.

Can you confirm the data_directories in the postgresql.conf files?

grep data_directory /etc/postgresql/*/main/postgresql.conf

If I followed your steps correctly I had to change it thusly:

postgres@me:~$ grep data_dir /etc/postgresql/*/main/postgresql.conf
/etc/postgresql/10/main/postgresql.conf:data_directory = '/var/lib/postgresql/10/data/postgresql0'      # use data in another directory
/etc/postgresql/9.5/main/postgresql.conf:data_directory = '/var/lib/postgresql/data/postgresql0'        # use data in another directory

to get to the final output:

Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade so,
once you start the new server, consider running:
    ./analyze_new_cluster.sh

Running this script will delete the old cluster's data files:
    ./delete_old_cluster.sh
  • Made the changes as you suggested in data_directory but now getting error connection to database failed: could not translate host name "." to address: No address associated with hostname – tuk Nov 15 '17 at 3:27
  • Can you please paste the output from ‘grep data_directory...’? And also share the full output from pg_upgrade_server.log – amacvar Nov 15 '17 at 4:45
  • - Updated the question with logs & conf. – tuk Nov 15 '17 at 6:11
  • seems like the cluster is running, message at 2017-11-15 05:55:38 UTC [20731-2] please stop it first sudo service postgresql stop and then re-run the upgrade – amacvar Nov 15 '17 at 6:20
  • Please check my EDIT 2 in the question. – tuk Nov 15 '17 at 6:45
