Description
## Enhancement
Dumpling and Lightning (logical mode) v8.4.0 supported the VECTOR type because the data type can be implicitly cast as a string. But such support is never tested (at least not visible in this repository), nor acknowledged in the documentation. There should be tests in the repo to ensure VECTOR columns can indeed be exported and imported.
### Further enhancement
Confirm that related features like LOAD DATA, SELECT INTO OUTFILE, IMPORT INTO, Lightning (physical mode), and BR snapshot also works? Especially when a table has vector index for the latter three.
