Yes, remove from index.

I think the exception should be raised.  What to do here is a policy  
decision that shouldn't be controlled at the index level IMO.   
Generally I'd prefer a transaction abort, a system exception, and a  
log entry, for instance.  When that's not acceptable, it's usually  
within a part of a transaction that I again can control with a  
savepoint, so that I revert to before the change that caused the  
reindex, log the error, and proceed.

I think and hope that what I'm describing for both situations is the  
status quo.
