The other thing to remember is that objectId is not a primary key in 
Object_*Overlap* tables. Recall that the concept of an overlap allows 
"duplicate" rows that differ only in subChunkId. This allows 
simpler/faster on-the-fly creation of subchunk tables.

We haven't thought about how this pseudo-duplication affects schema 
handling yet (because we have put very little thought into schema 
handling for non baseline LSST schema).
