Description:
Hi,
MySQL v9 seems to support the vector data type but I cannot see it in release notes, "1.4 What Is New in MySQL 9.0" or data types documentation.

You can turn off this feature to get a quicker startup with -A

Suggested fix:
Add documentation on new data type, usage and any associated functions.
