You have to shoot the old master in the head and re-establish the
master slave roles, reversed. Otherwise, you will encounter
"split-brain" madness. There are nice commercial solutions from
Wandisco that address precisely this situation: I'd highly recommend
using them instead of trying to brew this on your own, because
synchronizing and replicating other communications and failing over
gracefully can get quite tricky, and they've convinced me from their
explanations here that they're doing it correctly.
