That's about 30 hours from here. I might have to pass, for now. But if it's on Youtube I'd be interested.
I think I understand recursive CTEs well enough now from the description in the documentation and studying the code. I'm impressed at the brevity of your solution, although in practice it does not perform well. The far more complex implementation from Pasma performs better, I think largely because it applies rules to narrow the search space. My challenge now is to implement that feature in Andl.

I'll be giving a talk on CTEs this Saturday at the Southeastern Linuxfest (http://www.southeastlinuxfest.org/) during which I will explain and demonstrate how to write a simple CTE that solves a sudoku puzzle. If you cannot attend in person, I'm told that the talk will be streamed live to youtube. -- D.
