ExtSQL is not a new database server. It is a significant set of independently developed software additions and patches to the existing source code of both MySQL and PostgreSQL. It provides a new set of SQL language features that make it easy for a DBA to monitor and audit activity on a busy server and account for activity by user, database, or even connecting client host. It even includes the ability to store historical usage data in amounts and time intervals specified by the DBA. It is not a separate monitoring utility, but built into the core of both servers.
