CREATE OR REPLACE might be a better option, not with the "merge into the existing role" part, but rather as
drop+create. If a malicious actor has already added other roles to the role, or created a table with a malicious
triggerdefinition, the drop part will fail, which is good from a security viewpoint. Of course, the drop portion will
alsofail under other conditions which don't entail any security concerns, but maybe they could be addressed in a series
offollow-on patches?
I understand this idea is not as useful for creating idempotent scripts, but maybe it gets you part of the way there?
