How can I see all programs running under PyCharm's control?

As I am testing my Python scripts, I frequently drop and reload my test database.  I cannot drop the database unless there are no existing connections to the database.  Sometimes, even though I have stopped debugging all of the scripts I am testing, there are still instances of some of the scripts running and holding on to connections.  The only way to release them is to stop PyCharm.  When I do that I get popup boxes asking if I want to disconnect from processes that I didn't know were running.  How can I see a list of all processes under PyCharm's control so that I can stop them without exiting PyCharm?
