Background

Error Status Code usually means that the data for such row is all NULL. In such case, a return type must be an Option and must be specified by a user. Ideally we should not burden our users with such cases and we should programmatically ensure that when the DB query returns error-like status codes / results, data is not taken into account at all.

There might be some Read related changes for Doobie, especially because we'll be introducing an Option return type for data. This might be a good read:
