I've been long wanted to add declarative dependencies to tests: each
test file would declare what other tests it depends on, and we would
have a special clause to state "this one must not be run in concurrence
with anything else".  Of course, this is just wishful thinking at this
point.

The number of assertion failures in get_object_address without all the
sanity checks I added in pg_get_object_address was a bit surprising.
That's the whole reason I decided to add the test.  I don't want to
blindly assume that all cases will work nicely in the future,
particularly as other object types are added.
