if create MTMV `date_trunc(`xxx`,'month')` when related table is `range` partition,and have 3 partitions: ``` 20200101-20200102 20200102-20200103 20200201-20200202 ``` then MTMV will have 2 partitions: ``` 20200101-20200201 20200201-20200301 ``` when related table is `list` partition,and have 3 partitions: ``` (20200101,20200102) (20200103) (20200201) ``` then MTMV will have 2 partitions: ``` (20200101,20200102，20200103) (20200201) ```
