Preparing the Database Server for JDBC

Out of the box, Java does not support unix sockets so the PostgreSQL server must be configured to allow TCP/IP connections. Starting with server version 8.0 TCP/IP connections are allowed from localhost. To allow connections to other interfaces than the loopback interface, you must modify the postgresql.conf file's listen_addresses setting.

Once you have made sure the server is correctly listening for TCP/IP connections the next step is to verify that users are allowed to connect to the server. Client authentication is setup in pg_hba.conf. Refer to the main PostgreSQLâ„¢ documentation for details .
