pg_hba.conf is a configuration file used by PostgreSQL to manage client authentication. The "METHOD scram-sha-256" in pg_hba.conf refers to the use of the SCRAM-SHA-256 authentication method for client authentication.
SCRAM-SHA-256 is a secure password-based authentication mechanism that is based on the Salted Challenge Response Authentication Mechanism (SCRAM). This mechanism is designed to protect against password theft and eavesdropping attacks.
When a client connects to a PostgreSQL server, the server will check the pg_hba.conf file to determine whether the client is allowed to connect and what authentication method to use. If the METHOD in pg_hba.conf is set to scram-sha-256, the client will be required to authenticate using the SCRAM-SHA-256 method.
Overall, using the SCRAM-SHA-256 authentication method in pg_hba.conf can help to improve the security of your PostgreSQL database by ensuring that client connections are properly authenticated.
