Thanks for working on it! @jinxing64
Our current behavior is based on what the other traditional DBMS systems
do. Moving tables across different database is rare. For example, DB2 and
Oracle do not support it.

So far, we do not have a clean way to support our current behavior and the
Hive's behavior. Thus, we want to hold this until the community has more
requests.
The quality of this PR is very close to the one we can merge. You can patch
it to your local forked version.
