How to configure PostgreSQL to accept all incoming connections

Viewed 226114

I've got a PostgreSQL data base that I'd like to configure to accept all incoming connections regardless of the source IP address. How can this be configured in the pg_hba.conf file? I'm using postgreSQL version 8.4.

Configuration all files with postgres 12 on centos:

step 1: search and edit file

sudo vi /var/lib/pgsql/12/data/pg_hba.conf

press "i" and at line IPv4 change

host    all             all             0.0.0.0/0            md5

step 2: search and edit file postgresql.conf

sudo vi /var/lib/pgsql/12/data/postgresql.conf

add last line: listen_addresses = '*' :wq! (save file) - step 3: restart

systemctl restart postgresql-12.service
