Call RemoveEventNotifier when you no longer want the database to automatically register and unregister an interest in server events when it opens and closes a connection to the server. For example, TIBEvents automatically calls RemoveEventNotifier when you change its Database property. 

Notifier is the event notifier previously added to the database's internal list by a call to AddEventNotifier. 

RemoveEventNotifier removes Notifier from its internal list of event notifiers.
