Thanks. Those modifications all look pretty neat.

I'm inclined to stick with the current definition of what updatable
means in the information schema. I'm not entirely convinced that other
possible interpretations of the spec are any more valid, and it
certainly doesn't seem worth another initdb or a break with backwards
compatibility by changing it. At least we now have functions that can
give a more intuitive result for updatability.
