Changing one existing option to mean something entirely different
should be avoided, as this could lead to silent breakages. As the
origin of the problem is that the option --role means "IN ROLE" in the
SQL grammar, we could keep around --role for compatibility while
marking it deprecated, and add two new options whose names would be
more consistent with each other. One choice could be --role-name and
--in-role-name, where --in-role-name maps to the older --role, just to
give an idea.
