The Network Configuration Manager database (PostgreSQL) uses an access list to limit access to the database. The access list is automatically generated based on the user's selections during the installation process.
If the product is configured so that the application server and database reside on the same server, the database access list only allows local connections over the loopback address. If the application server is remote from the database, the installer adds an entry in the access list for the remote servers and modifies the PostgreSQL configuration so that it listens on the external network interface.
