Here's a v4 of that patch.  I added support for DROP OWNED, and added
object name and schema name available to the pg_dropped_objects
function.

Since we're now in agreement that this is the way to go, I think this
only needs a few more tweaks to get to a committable state, as well as
some useful tests and doc changes.  (v3 has docs which I didn't include
here but are probably useful almost verbatim.)

Do we want some more stuff provided by pg_dropped_objects?  We now have
classId, objectId, objectSubId, object name, schema name.  One further
thing I think we need is the object's type, i.e. a simple untranslated
string "table", "view", "operator" and so on.  AFAICT this requires a
nearly-duplicate of getObjectDescription.
