Description

For example, in the following DDL statements, default database name is recognized as DEFAULT instead of default.

CREATE TABLE DEFAULT.TABLE1 (xxx INT, ...

The main reason is default is non-reserved keywords. So, it is not passed through the same case sensitive handling code. So, we should fix it.
