enable postgresql server to listen on all addresses

Out of the box, the postgresql server listens to localhost / 127.0.0.1 In order to make the server listen to all addresses on the machine, in postgresql.conf, replace listen_addresses = 'localhost' with listen_addresses = '*' or supply the complete list of IPs, like i.e. listen_addresses = '127.0.0.1,192.168.0.10'.

enable scram-sha-256 for password hashing

if your PostgreSQL configuration still uses md5 for password hashing, the config should be changed to use scram-sha-256 for password hashing in postgres.conf with password_encryption = scram-sha-256
