Ah, so you upgraded a month ago, not one week ago, right?

I'm betting this is the problem.  The 9.3 cluster should have
oldestMulti=20783, but instead it has oldestMulti=1.  Either pg_upgrade
is misreading the nextMulti value from the old cluster, or pg_resetxlog
is failing to set oldestMulti appropriately ... or something funny
happened to pg_control in the meantime.  I just ran a quick test, and I
see that pg_upgrade is setting oldestMulti correctly (to the old
cluster's NextMultiXactId value) in the new cluster when upgrading from
9.1.
