Not sure about your position here. You claimed that it would be a good idea to
freeze the on disk format for at least a couple of versions. Do you argue
here that this cycle shouldn't start with the next version, or did you
reverse your thought ?
If the former, I think you're right. There are some too big changes close to
being made - if I have read this list correctly. Table spaces and PITR would
certainly change it.
But if the freeze could start after 7.5 and last two-three years, it might
help things.
