Thanks for your reply. Is this something that I can request as a feature add? I don't think it should be too much of effort (based on my limited source code knowledge), but I'm not familiar with the process to request a feature.
although there is not flag in command line, but you always run the alter <something> rename to <something else> for role and schema post restore.
i can be corrected, if i am missing anything. i tried with pagilla db, but just keeping it simple here.
PS: pg_hba.conf needs to be updated with new role/user post restore, or else user will not be able to connect.
postgres@db:~/playground/demo$ createdb demo
postgres@db:~/playground/demo$ createuser demo
postgres@db:~/playground/demo$ pg_restore -d demo demo.db -- some dummy restore which has objects owned by demo user in demo schema
postgres@db:~/playground/demo$ psql demo

---the below to sql statements will probably do what you want in your restore command line flag, you need not edit dump file by hand imho
demo=# alter schema demo rename to production;
ALTER SCHEMA
demo=# alter role demo rename to production;
ALTER ROLE
