OK, for those who haven't followed COLO for so long; 'continuous
replication' is when after the first primary fails, you can promote the
original secondary to a new primary and start replicating again;
i.e. current COLO gives you
p<->s
<primary fails>
s
with your patches you can do
s becomes p2
p2<->s2
and you're back to being resilient again.
Which is great; because that was always an important missing piece.
Do you have some test scripts/setup for this - it would be great
to automate some testing.
