As Andrew says, the part about the CSV format is not correct, but I also don't think I agree with the larger point, either. I believe that round-trip safety is a really desirable property. Is it absolutely necessary in every case? Maybe not. But, it shouldn't be lacking without a good reason, either, at least IMHO. If you postulate that people are moving data from A to B, it is reasonable to think that eventually someone is going to want to move some data from B back to A. If that turns out to be hard, they'll be sad. We shouldn't make people sad without a good reason. -- Robert Haas EDB: http://www.enterprisedb.com
