How to configure PostgreSQL to accept all incoming connections

0.0.0.0/0 for all IPv4 addresses

::0/0 for all IPv6 addresses

all to match any IP address

samehost to match any of the server's own IP addresses

samenet to match any address in any subnet that the server is directly connected to.

e.g.

host    all             all             0.0.0.0/0            md5

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();

Note: to change listen_addresses, a reload is not enough, and you have to restart the server.
