That is exactly the behavior for which I am arguing. Stephen also wants a warning, but I disagree, because the warning is totally non-actionable. It tells you that some tool, at some point in the past, did something bad. You can't do anything about that, and you wouldn't need to except for the arbitrary decision to label duplicate lines as bad in the first place. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
