Comment (by strk):

 There's still a pending issue: renamed functions (not drop) are left
 pointing to possibly unexisting library:

 This may be a problem in production as the users's views might be just
 disfunctioning unless the old ones point to the same major version as the
 new ones (and we didn't change function name in the library).

 For the testcase it could be only fixed by adapting those views (either
 automatically or by the test itself, maybe upgrading against after having
 dropped the views)
