> We should support defining a partitioning specification for materialized views and that
the results of the materialized view evaluation are stored meeting the partitioning spec.

> The syntax should be extended as follows:
> {code:sql}
> CREATE MATERIALIZED VIEW [IF NOT EXISTS] [db_name.]materialized_view_name
>   [COMMENT materialized_view_comment]
>   [PARTITIONED ON (col_name, ...)] -- NEW!
>   [
>    [ROW FORMAT row_format] 
>    [STORED AS file_format]
>      | STORED BY 'storage.handler.class.name' [WITH SERDEPROPERTIES (...)]
>   ]
>   [LOCATION hdfs_path]
>   [TBLPROPERTIES (property_name=property_value, ...)]
>   AS select_statement;
> {code}
