Thoughts? > PostGIS has some rarely used box operations as part of GiST opclass, like "overabove". These are source of misunderstanding, as it hinges on the fact that non-square geometry will be coerced into a box on a call, which is not obvious when you call it on something like diagonal linestrings. It may happen that we will decide to remove them. On such circumstances, I expect that ALTER OPERATOR CLASS DROP OPERATOR will work. Other thing that I would expect is that DROP FUNCTION ... CASCADE will remove the operator and unregister the operator from operator class without dropping operator class itself.
