I think everyone agrees on that. The issue is that I don't know how to implement the optimization Peter wants without changing the query semantics, and it seems like Alexander doesn't either. By committing the patch without that optimization, we're *avoiding* changing the query semantics. -- Robert Haas EDB: http://www.enterprisedb.com
