db0->db1 in synchronous mode

The idea is that we know that data on db0 is not written until we know for a
fact that db1 also has that data. That is great and a guarantee of data
integrity between the two nodes.

That guarantee is never there. The only thing guaranteed is that the
client isn't notified of the commit until db1 has received the data.

Well ugh on that.. but that is for another reply.

That's why you should configure a second standby as another (candidate)
synchronous replica, also listed in synchronous_standby_names.

I don't have a response to this that does not involve a great deal of sarcasm.
