**        due to ticket [2f7170d73bf9abf80] from 2015-02-09.)

**        or the subquery is not itself a join and the outer query is not
**        an aggregate.
**
**   (4)  The subquery is not DISTINCT.

**        sub-queries that were excluded from this optimization. Restriction

  ** query cannot be an aggregate.  This is an artifact of the way aggregates
  ** are processed - there is not mechanism to determine if the LEFT JOIN
