When you do an immediate stop, all users have their transactions aborted and all connections are disconnected. There is no clean shutdown, nor is there politeness of any kind.
An immediate mode stop is similar to a database crash. Some cached files will need to be rebuilt, and the database itself needs to undergo crash recovery when it comes back up.
