# recognize 'ALL' as a valid privilege name. So we probably need to
# hard-code a mapping between 'ALL' and the list of actual privileges that
# it entails, and loop over them to check them. That sort of thing will
# probably need to wait until we port this over to ruby, so, for now, we're
# just going to assume that if they have "CREATE" privileges on a database,
# then they have "ALL". (I told you that it was terrible!)
