DROP CASCADE doesn't currently promise to visit dependent objects in a fixed order, so when the regression tests use it, we typically need to suppress the details of which objects get dropped in order to have predictable test output. Traditionally we've done that by setting client_min_messages higher than NOTICE, but there's a better way: we can "\set VERBOSITY terse" in psql. That suppresses the DETAIL message with the object list, but we still get the basic notice telling how many objects were dropped. So at least the test case can verify that the expected number of objects were dropped. The VERBOSITY method was already in use in a few places, but run around and use it wherever it makes sense.
