Ok, so it is best to "manually" fill the content of the database instead 
of trying to rely on
bucardo to do this.
In other words, doing something like this is a bad idea:
1. bucardo add sync foobar relgroup=myrels dbs=A:source,B:target
2. wait / check the state of the sync / other
3. bucardo update sync foobar dbs=A:source,B:source

Is it plan to implement the onetimecopy for multiple source mode to make 
bucardo do this kind of work under the covers?
