Ron, the tests that I've seen offer no support for that thesis. If you
want us to accept such a blanket statement as fact, you'd better back
it up with evidence. Let's see some test cases.
Postgres certainly has plenty of performance issues, but I have no
reason to believe that the fundamental MVCC mechanism is one of them.
