What I've done
CREATE ROLE superrole WITH NOLOGIN SUPERUSER ..;
CREATE USER nosuperuser WITH LOGIN NOSUPERUSER INHERIT ..;
GRANT superrole TO nosuperuser WITH ADMIN OPTION;
REVOKE CONNECT ON DATABASE nonpublicdb FROM public ;
psql -d postgres -U nosupuser
postgres=# set role superrole;
postgres=# \c nonpublicdb
FATAL: permission denied for database " nonpublicdb "
DETAIL: User does not have CONNECT privilege.
I expect that the connection to the database is allowed since a role with superuser is used. (I don't' expect any difference between using a role (including superuser) or a user (including superuser).)

Please provide more details about what this step #2 actually means.

Details about exactly what you're doing to connect here would be helpful.

CONNECT privileges are needed to be able to connect to the database, so it's not surprising that you needed to GRANT them to the user after REVOKE'ing them from PUBLIC. What's not clear is what you're actually trying to do and what you're expecting to work that apparently isn't.
Thanks!
Stephen
