    @liming01 really good points for (1). I'm not sure what versions you are 
referring to in (3). What I was getting at was that for users upgrading from 
1.3.x to 2.x, the hawq_toolkit view should also be CREATE OR REPLACE'd. But if 
we have a bigger story for upgrade c.f. @GodenYao, we can be more confident on 
the use case.

> Since the hcatalog database is not a normal database, it would cause some 
> errors when querying hawq_toolkit.hawq_size_of_database.
> Following is an example:
> SELECT * FROM hawq_toolkit.hawq_size_of_database;
> ERROR:  database with OID 6120 does not exist (dbsize.c:219)
> OID 6120 database is the hcatalog database.
