> JoniToMultiJoinRule collapses multiple INNER joins into a single MultiJoin.
> I was wondering if all the joins are full outer joins, couldn't we use the
> same logic to allow MultiJoins to contains multiple FULL joins? This would
> allow LoptOptimizeJoinRule to re-order full outer joins, just like inner
> joins.
