I don't understand why this is controversial.  In the current code, if
you have a master and a single sync standby, and the master disappears
and you promote the standby, now the new master is running *without a
standby*.  If you are willing to let the new master run without a
standby, why are you not willing to let the
the old one do so if it were the standby which failed in the first place?

Cheers,

Jeff
