According to https://github.blog/2020-05-20-three-bugs-in-the-go-mysql-driver/, when QueryContext is called with a context that is cancelled during scan, you can receive incomplete or corrupted results. As I understand it, the corruption is fixed upstream, but it's still possible to get incomplete results that will only show up in the error result from Close. It's still possible and correct to call `defer rows.Close()`, since the database/sql docs say this: https://godoc.org/database/sql#Rows.Close > Close is idempotent and does not affect the result of Err.

QueryContext is called with a context that is cancelled during scan, you
can receive incomplete or corrupted results. This can cause security bugs.
As I understand it, the corruption is fixed upstream, but it's still possible
