1) You can't tell whether the update has been applied or not
Actually, Simetrical and I discussed this, and we determined that something like
"SELECT 1 FROM pagelinks WHERE pl_namespace=0 AND pl_title='' LIMIT
1;" would work okay, although it's admittedly not ideal. The update
doesn't really hurt anything if it's run multiple times, either -- the
way the update works is that it will add a bogus entry for any page
with no entries whatsoever (not even bogus ones).
