In my opinion, such a derivative is no more "dependent" upon
proprietary database software than it is on its operating system.
The OS and the DBMS are both independent programs with which
your software communicates and interacts to do what it does.
Do you think the OS should be as free/open as the DBMS people
want to use with your software?

OSD #9 says that you can impose restrictions on derivative works
of your software, but not on other software that it interacts with.
