The match on ColumnFlags::UNSIGNED_FLAG would only work if UNSIGNED_FLAG was the only flag set.
If any other flag were set, such as the NOT_NULL flag, then it wouldn't match and the value would thus be coerced as an i32 instead. In the case of a u32, it would overflow, leading to upsert issues in the QE (and probably more issues).
