It's a commonly requested feature. Personally I think it's kind of silly, but I've had multiple people ask me for it or how to do it too. So whether or not it's really effective/useful, it's in demand. Personally I'd rather see it as part of an extension that does other filtering, I don't find it compelling for core. But I don't really object either. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
