Description

Feature Request

What

I'd like to handle vector columns in MariaDB (https://mariadb.com/kb/en/vector-overview/)

Why

It would be useful for handling vector searches on Doctrine entities

Contributor guide

Research direction
Investigate MariaDB's VECTOR type and how Doctrine DBAL handles custom types. Examine existing type implementations (e.g., for PostgreSQL arrays) as a pattern. Then implement a new MariaDB specific type class for vector columns, including mapping, schema representation, and platform support.
