So you've already moved the goalposts from what was claimed in your
prior message.  If the data is not maintained (with 100% reliability)
during ALTER TABLE, how are you going to do something like "figure out
missing columns"?

I can see the potential usefulness of a self-documenting table storage
format, but this proposal isn't that; it's just an unreliable kluge.
