[Bucardo-general] bucardo 5 master-master sequence odd/even?

[Jonathan Brinkman]

Greetings
When using bucardo4 with swap syncs we were instructed to set each side of
the swap to use dissimilar primary key ranges so that the swap would never
create a conflict. Like Master-A uses even keys and Master-B uses odd keys
(Increment 2).
Do we still need to do that with bucardo5 in a Master-Master sync?
We are seeing primary key conflicts when Master-B creates a new record and
apparently isn't having its sequence updated properly when Master-A
previously created a record (and used that primary key already).
Thanks again
Jonathan
