Your best solution is to offset the sequences that are making the primary 
keys, such that both count by two but one does even and one does odds.
So the master database would so something like:


Do the same thing on the remote database, but call nextval() as needed 
to make sure it is even if the master is odd, and vice versa.

Just include all the tables in the sync and you will be good.
