Wow. I didn't even consider that's what was being asked. (Does that
make me sane?) I had assumed he mean the rows would be ordered in the
order of the columns. For example,

select foo, bar, baz
from blurfl

would be (by default) equivalent to

select foo, bar, baz
from blurfl
order by foo, bar, baz.

Thanks, Florian (and Andreas) for the sanity check. (Still haven't
heard back from the OP though.)
