DROP EXTENSION didn't properly reset caches and other saved state causing various errors related to bad state when the extension was dropped and/or recreated later. This patch adds functionality to track the state of the extension and also signals DROP EXTENSION to other backends that might be running, allowing them to reset their internal extension state.
