login as root

[root@Node0 ~]$
[root@Node0 ~]$ cd /var/lib/pgsql  
[root@Node0 ~]$ su - postgres 
[root@Node0 pgsql]$ sudo su  - postgres
-bash-4.2 $ grep listen /var/lib/pgsql/data/postgresql.conf

#listen_addresses = 'localhost'		# what IP address(es) to listen on;
-bash-4.2 $ vi /var/lib/pgsql/data_bkp/postgresql.conf

Find listen_address= 'localhost' and change to local_address='*', then and exit vi, then exit back to root.

service postgresql restart

Redirecting to /bin/systemctl restart postgresql.service

[root@Node0 ~]$ ambari-server setup

and accept all prompts, and when ambari-server setup will successfully complete,

[root@Node0 ~]$ ambari-server start 

Ambari Server 'start' completed successfully.

Thank you!!!... The steps worked for me.
I have small question, my linux server on which the ambari-server is running rebooted as it went unresponsive, so in this how only postgresql service stopped and other all services were running? any idea?

ambari-server start

On running the above command, I was encountering the same error while starting Ambari-server, where ambari failed to start the Postgresql server with error 3.

I figured out the following solution to start ambari-server.

You can check the status using

service postgresql status

This gives the status of the service running as PostgreSQL. In case this is giving the error that the service is not running and the server failed to start, you can check the reason with the following commands:

systemctl status postgresql.service

If the reasons show anything related to the port and the listener like:

Then navigate to the following path and check the versions:

ls /var/lib/pgsql

In case you find other folders like 9.6 or 9.5, for example, 9.6, then try and check if postgresql-9.6 is running.

service postgresql-9.6 status
systemctl status postgresql-9.6.service

In case you find that this is running, you will have to stop the service and chkconfig it to off.

service postgresql-9.6 stop
chkconfig postgresql-9.6 off

Try and restart the ambari-server now and this might work, as the ambari server tries to start the postgresql using /var/lib/pgsql/data/postgresql.conf and not the 9.6 version configuration. In order to stop facilitate the server to use the default configuration, we have to stop the server on 9.6 version or point ambari to 9.6 version pgsql.
