That command will only add *tables* to the things Bucardo knows to
replicate. The bucardo command also has an "add all sequences" operation,
which you should not perform for your scenario.

Both databases should have all of your tables and sequences, but Bucardo
should be configured to replicate only the tables.
On db1, you then set the sequences to issue only *odd* numbers. ("ALTER
SEQUENCE foo START 1 INCREMENT 2;" — produces 1, 3, 5...)
On db2, you set them to issue only *even* numbers. ("ALTER SEQUENCE foo
START 2 INCREMENT 2;" — produces 2, 4, 6...)
