Liten / Notify

Hi, I've seen the support for Listen/Notify is there since 3.00 version. Maybe I missed something but how the command LISTEN is implemented. The handling of notifications is implemented as PgSqlConnection event, but how to "subscribe" to listen?

You should execute PgSqlCommand with "listen" keyword. This will subscribe you to the event. When notification trigger in your database fires, you will get Notification event in PgSqlConnection. Note that asynchronous notifications are not supported yet, so you'll need to execute something to get notification event.
