A service file setting overrides the corresponding environment variable, and in turn can be overridden by a value given directly in the connection string.

If the same service name exists in both the user and the system file, the user file takes precedence. By default, the per-user service file is named ~/.pg_service.conf . On Microsoft Windows, it is named %APPDATA%\\postgresql\\.pg_service.conf (where %APPDATA% refers to the Application Data subdirectory in the user's profile). A different file name can be specified by setting the environment variable PGSERVICEFILE . The system-wide file is named pg_service.conf . By default it is sought in the etc directory of the PostgreSQL installation (use pg_config --sysconfdir to identify this directory precisely). Another directory, but not a different file name, can be specified by setting the environment variable PGSYSCONFDIR .", "Connection parameters obtained from a service file are combined with parameters obtained from other sources. A service file setting overrides the corresponding environment variable, and in turn can be overridden by a value given directly in the connection string. For example, using the above service file, a connection string service=mydb port=5434 will use host somehost , port 5434 , user admin , and other parameters as set by environment variables or built-in

The following methods may be specified: password The server must request plaintext password authentication. md5 The server must request MD5 hashed password authentication. gss The server must either request a Kerberos handshake via GSSAPI or establish a GSS -encrypted channel (see also gssencmode ). sspi The server must request Windows SSPI authentication. scram-sha-256 The server must successfully complete a SCRAM-SHA-256 authentication exchange with the client. none The server must not prompt the client for an authentication exchange.
