Creates a table function definition.
You must have explicit CREATE FUNCTION privileges on the database in which the table function is to be contained to perform the CREATE FUNCTION statement.
The system does not grant the CREATE FUNCTION privilege automatically when you create a database or user: you must grant that privilege explicitly.
CREATE FUNCTION is not granted implicitly on the databases and functions owned by a database or user unless the owner also has an explicit WITH GRANT OPTION privilege defined for itself.

- DROP FUNCTION
- EXECUTE FUNCTION
