Hello list,

I've started using libpqxx some days ago and had no problem doing the basic stuff so far... Right now i'm trying to code a simple test program to do something when it receives a notification from the db. I was looking into examples provided in the src/test directory of my libpqxx 3.0 installation, specifically test004.cxx file. There i can see a class named TestListener wich inherits from class notify_listener. Since i couldn't find the latter class on the documentation, i assume it doesn't exist and it's just for demo. Am i correct assuming that? If so, what would this class be? A trigger? A transactor?
Any directions regarding better understanding of notify/listen would be appreciated.

Thanx!
