Well, we've changed it when there was a benefit to an existing tool to do so. So far that's meant page header and tuple header changes. If we ever had a working in-place upgrade solution, I think we'd be willing to make the page version account for datatype format changes too. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
