54cda4edbe Disable the query flattener optimization for SELECT statements that are on 
the RHS of vector IN operators.  This is a hack that fixes the bug
described in ticket [da7841375186386c]. A better solution that does not
disable the query flattener is needed, but this will server for the time
being.
