Agreed. But going back to my point, how do we know what field to set the
array key on? Key on the first field selected? Or scrap the idea of
hashes and just chuck them into a numeric array, knowing that in some
(most?) cases you'll need to loop through it again to make the hash what
you want? It would be nice for someone who is in support of a
db_fetch_all() function to maybe grep through core/contrib looking for
examples of this and come up with a sane default behaviour.
