** OBSOLETE COMMENT 2:
** Restriction 12: If the subquery is the right operand of a left outer
** join, make sure the subquery has no WHERE clause.
** An examples of why this is not allowed:
**
** t1 LEFT OUTER JOIN (SELECT * FROM t2 WHERE t2.x>0)
**
** If we flatten the above, we would get
**
** (t1 LEFT OUTER JOIN t2) WHERE t2.x>0
**
** But the t2.x>0 test will always fail on a NULL row of t2, which
** effectively converts the OUTER JOIN into an INNER JOIN.
**
** THIS OVERRIDES OBSOLETE COMMENTS 1 AND 2 ABOVE:
** Ticket #3300 shows that flattening the right term of a LEFT JOIN
** is fraught with danger. Best to avoid the whole thing. If the
** subquery is the right term of a LEFT JOIN, then do not flatten.
