    I added some columns and index to ``PARTITION_KEYS`` table for getting 
partitions efficiently and tested on macbook successfully. The batch response 
time results are listed below.
    
    * 3,000 records: 1 ~ 2 sec
    * 30,000 records: 6 ~ 8 sec
    * 300,000 records: 60 ~ 70 sec
    
    Honestly, I was worried about removing foreign key of ``PARTITION_KEYS`` 
table because it affected to batch insert performance. But it would be good to 
leave it on the table because of data integrity.

> Currently, If new partitions are added to HDFS by ColPartitionStoreExec, 
> CatalogStore will not be aware of these partitions. So, Tajo need to load 
> newly added partitions automatically to CatalogStore by running insert query 
> or CTAS query.
