During my review and time spent working on the functional dependencies part of extended statistics I wondered what was the use for the pg_stats_ext view. I was unsure why the length of the serialised dependencies was useful.
Perhaps we could improve the view, but I'm not all that sure what value it would add. Maybe we need to discuss this, but in the meantime, I've attached a patch which just removes the view completely -- David Rowley http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
