I was thinking along the lines of what Jim had suggested earlier regarding
overflow partition. Instead of dumping unmatched rows to the master table,
we could put them into a default "DUMP/DUMB" partition.
Given that Simon wants to do away with having the master table APPENDed in
the planning phase, this would be better.
