Can you try to implement it without changes in DataType and get/set mapping?

The idea would be to use DataType.OBJECT and use a custom AttributeConverter where the context is JdbcConversionContext/R2dbcConversionContext there we should probably also add the current dialect; by that we can fetch some dialect specific vector helper. (See PostgresEnumsSpec as an example to use it).
The vector data classes should be annotated with @TypeDef. We might want to introduce a new runtime interface that can also be implemented by AttributeConverter to let the schema generator know what type to put.

The idea would be to implement it in almost non-invasive way so other things like geo etc can be supported as well easily.

+
+Supported platforms (since 5.0.0):
+- Oracle Database 23ai VECTOR columns (JDBC and R2DBC)
+- PostgreSQL pgvector (JDBC and R2DBC)


we need to add MySQL vector support as well

added only for jdbc

Use TypeDef

it can't be used since the property doesn't have TypeDef it has only MappedProperty and data from TypeDef was copied to MappedProperty in the visitor
