Logical column ordering seems like a rather clean solution. The system
could also make educated decisions such as storing fixed size attributes
before variables sized ones. Kind of like a Cluster within the table.

I still think that fixing this in pg_dump might be the path of least
resistance, but we've got until autumn(?) to figure it out.
