Bucardo provides a very capable control mechanism in the bucardo command-line tool. Unlike Slony, which depends on an arcane programming language to create new replication sets and subscriptions, Bucardo is much more straightforward. As with Slony, we still want to copy data to other servers to avoid overwhelming our primary server.
In this recipe, we will utilize bucardo to create what Bucardo refers to as a dbgroup and relgroup. A Bucardo dbgroup consists of multiple databases in a provider-subscriber relationship, and a relgroup contains one or more tables. These are the basis of its synchronization system.
