Postgres and MySQL are very different in these respects. Answering these questions is rather pointless, as it will not give you an understanding of how the role and grant system works in PostgreSQL and you'll need that kind of understanding if you're as concerned about security as you appear to be.

Have a look at chapters 19 & 20 in the fine manual: http://www.postgresql.org/docs/9.2/static/index.html
