Review Comment:
Add a `SELECT *` test query? Just want to make sure that the output schema
doesn't include `qid` or `struct`, or unwanted columns, or wrong column name
(e.g., with the `Generator` alias).
> SELECT *
> FROM users u JOIN products p
> APPROX NEAREST 1 BY SIMILARITY -abs(u.score - p.pscore);
