I agree. My original post to this thread was more of a throw-away comment than anything, and I'm not attacking the feature. I didn't think it was a very clear example and, TBH, I still don't. But I don't want to blow that up into a big debate on the virtues of this feature, which I never intended to question, or on the correctness of the patch, which I also did not intend to question. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
