certainly, if your goal is a pgreplicator style multi-master async, this
is correct, as you have to make decisions about the direction of
data flow, id generation, and conflict resolution up front.
if you want slony-I style single master/multi slave, you don't have to
do so much advance thinking as records are only being inserted into
the system on the single master.
