I have installed Postgres-11 on a host of RedHat Linux 7, and it had been initialized and started OK.
Then I added listen_addresses = '*' into the configuration file at /var/lib/pgsql/11/data/pg_hba.conf, hoping to let Postgres listen on a non-local interface. However, when trying to restart Postgres by command systemctl restart postgresql-11, it always gets the below error about "Unregistered Authentication Agent".
I tried to remove listen_addresses = '*' and everything went back to normal again.
Not sure what is wrong here, and any hints will be highly appreciated.
