46133d98a6 Do not use the flattening optimization for a sub-query on the RHS of a LEFT 
JOIN if that subquery reads data from a virtual table. Because it prevents the
planner from creating an automatic index on the results of the sub-query, the
flattening optimization sometimes slows things down in this case.
