connect to PostgreSQL server: FATAL: no pg_hba.conf entry for host

Add or edit the following line in your postgresql.conf :

listen_addresses = '*'

Add the following line as the first line of pg_hba.conf. It allows access to all databases for all users with an encrypted password:

# TYPE DATABASE USER CIDR-ADDRESS  METHOD
host  all  all 0.0.0.0/0 md5

Restart Postgresql after adding this with service postgresql restart or the equivalent command for your setup.

This solution works for IPv4 / IPv6

nano /var/lib/pgsql/data/pg_hba.conf

add at final

host all all      ::1/128      md5
host all postgres 127.0.0.1/32 md5

and then restart postgresql service

/etc/init.d/postgresql restart

The way I solved this was:

Added the line as below in pg_hba.conf:

hostnossl    all          all            0.0.0.0/0  trust        

and this was modified in postgresql.conf, as shown:

listen_addresses = '*'  

I had this instance running on a Centos 7.3 and Postgres 9.5 in a VM in Azure, given this was a POC (proof of concept) you won't want to connect without SSL in your actual prod environment.

To connect to the instance I was using pgAdmin 4 on macOS Sierra.
