Yeah, if it's not in there already. I remember seeing some Berkeley-era
comments speculating that this would be a good thing to do. Not sure if
they're still in the code, or
I believe that really what you want is fixed-width NOT NULL columns
first, then fixed-width nullable, then var-width. This ordering will
improve the odds of actually being able to use the fixed offset for
a particular column.
