Agreed --- I committed what I had, anyone want to volunteer for
refactoring the execution of DropStmt?

After looking again, I think that this is not technically very
difficult, but coming up with something that looks tasteful to everyone
might be tricky. In particular I didn't see a nice way to do it without
using struct ObjectAddress in a bunch of header files that don't
currently include dependency.h. A possible response to that is to move
ObjectAddress into postgres.h, but that seems a bit ugly too.
