I changed it since this refers to the value of the COMMENT clause in the CREATE DATABASE statement.
I changed it back to the original value just to keep things simple.

namespaces (databases or schemas) such that users can create tables in their specific namespaces.
These name spaces can have different warehouse directories (with a default naming scheme)
and possibly different properties.
