How to configure PostgreSQL to accept all incoming connections

Question

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

Answer 1

Just use 0.0.0.0/0.

host    all             all             0.0.0.0/0            md5

Make sure the listen_addresses in postgresql.conf (or ALTER SYSTEM SET) allows incoming connections on all available IP interfaces.

listen_addresses = '*'

After the changes you have to reload the configuration. One way to do this is execute this SELECT as a superuser.

SELECT pg_reload_conf();
