The main algorithm is followed as : - pick an anchor relation (i.e., target relation) - per each target shard interval - add the target shard interval's shard range as a restriction to the relations (if all relations joined on the partition keys) - Check whether the query is router plannable per target shard interval. - If router plannable, create a task	2017-04-11 13:56:04 +03:00

Enabling physical planner for subquery pushdown changes

This commit applies the logic that exists in INSERT .. SELECT
planning to the subquery pushdown changes.

The main algorithm is followed as :
   - pick an anchor relation (i.e., target relation)
   - per each target shard interval
       - add the target shard interval's shard range
         as a restriction to the relations (if all relations
         joined on the partition keys)
        - Check whether the query is router plannable per
          target shard interval.
        - If router plannable, create a task
