I don’t have a copy of 2016 handy, unfortunately, and so I’m not sure if it’s described that way in a “stable” version of the standard or not (it isn’t defined in the 2006 draft I’ve seen), but ultimately I don’t think we are really talking about entirely net-new syntax here…

Do bob's objects get dropped, do they get orphaned, or do they get assigned to some other owner? I would expect that they get dropped, but I'd like to know what the spec says about it before going any further with this discussion.
While the spec does talk about roles and how they can own objects, such
as schemas, the 'drop role statement' doesn't appear to say anything
about what happens to the objects which that role owns (in any case
of CASCADE, RESTRICT, or no drop behavior, is specified).
Thanks,
Stephen
