Ecto `insert()` with `returning: true` on Postgres - request for clarification

Thank you! Also, I just found this below, posting here for future reference of others:

While the above won’t raise an error in case of conflicts, it also won’t update the struct given, so it will return a tag without ID. One solution is to force an update to happen in case of conflicts, even if the update is about setting the tag name to its current name.
