The System Domain of the Postgres database is a special domain that contains the configuration data of the Security Management Server and the Log Servers. It includes information such as the trusted GUI clients, the administrators, the licenses, the global properties, and the audit logs. The System Domain is not accessible by the user and can only be modified by the Check Point processes. The user modified configurations, such as network objects, policies, and rules, are stored in the User Domain of the Postgres database. The saved queries for applications are stored in the Application Domain of the Postgres database.
