Review Comment:
The incremental materialized view maps snapshot information through mvName
and does not retain partition information. If the materialized view table type
is partitioned, the relevant information corresponding to mvName ->
MTMVRefreshPartitionSnapshot will be removed. Therefore, it is necessary to add
mvName here to ensure that mvName -> MTMVRefreshPartitionSnapshot is not deleted
