AFAIK, the only solution is to follow the initial standby setup
process to bring the standby up to sync with the new master. One
small comfort is that since the standby is mostly in the state it
needs to be, an rsync based process might happen fairly quickly. This
of course means that if you lose the new master before the standby is
up to speed you are facing data loss. I'm really curious if anyone
has figured out a potential solution to this problem.
