Generally if a role is granted membership to another role with NOINHERIT they must use SET ROLE to access the privileges of that role, however with predefined roles the membership and privilege is conflated. Fix that by replacing is_member_of_role with has_privs_for_role for predefined roles. Patch does not remove is_member_of_role from acl.h, but it does add a warning not to use that function for privilege checking. Not backpatched based on hackers list discussion.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
