It should not. Its purpose is to list which syncs are replicating 
from which tables. Because more than one sync can potentially 
operate on a table, we cannot clean the delta tables until we 
know that the rows in question have been replicated by every 
sync using that table. Since a sync has no way of knowing about 
other syncs, we defer that cleanup and use the bucardo_delta_targets 
table to coordinate between them.

It should be a small table, and contain a single entry for 
each sync/table combination you are using. If it has duplicates 
or other wrong information, just manually clean it out.
