+-- Test earthdistance extension

+-- That's really exercising the core database's dependency logic, so ideally
+-- we'd do it in the core regression tests, but we can't for lack of suitable
+-- guaranteed-available extensions. earthdistance is a good test case because
+-- it has a dependency on the cube extension.
