Hello,

Someone in the French community recently used some basic SQL command with
Postgis to eliminate obvious merge problem. It worked better than we
expected. Maybe you would be interested.
http://wiki.openstreetmap.org/wiki/BMO contains most of the information
about how the differential import was done.
