We're having on-site PostgreSQL training from Simon Riggs of 2nd Quadrant.
It's a bit different having training from someone who really knows what they're talking about. Other trainers may "know" their product well enough to train, install and troubleshoot it, but this guy knows the guts of the system being one of the contributors to it. (Not that he's full of himself nor is he mentioning it all the time or anything like that - he's humble and a likeable guy).
It's a damn fine course, and I'd recommend getting PostgreSQL training from these people any day. Props to them.
