Re: Callbacks for NOTIFY

Johann,

I do not know of anyone else working on this, but this has come up a 
couple of times in the past so I could be mistaken.  You might want to 
check the email archives.

I think this functionality would be an interesting addition to the 
driver.  So I encourage you to investigate if you have the interest. 
Once you get a firm idea of what you want to do, I would suggest sending 
your ideas/design to this list for feedback.  Getting feedback early on 
and working that feeback into your patch is the best way of insuring 
that what you build can and will get incorporated.

Having said that, I think there are some real challenges in getting this 
done due to how notifications are handled by the database.  Specifically 
 how do you get the notifications to the client without having the 
client poll the server for new notifications.

thanks,
--Barry
