Ok, this is what I was looking for. If we are serious about this, would it make sense to start a new policy of bumping the major version number every time an upgrade requires a dump / reload? So PostgreSQL 8.0 would be the next version with on-disk changes, all the 8.x releases would have the same on-disk format, and the next time the disk format changes, then we are on 9.0. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
