There was an interesting issue recently opened. The user made several interesting decisions that to my view can be useful for all ( click to see ): Spatial types . Not only Postgres has a rich GIS/Spatial support, the driver offers dedicated types, to make the experience as smooth as possible. Batch insert with ON_CONFLICT clause - making the insertion pipeline very efficient. RETURNING clause. Since the ON_CONFLICT clause's action is DO_NOTHING , the clause will return all the INSERTed rows. I believe that it filters out a substantial part of objects, so it effectively reduces the amount of work that needs to be performed with the output (instead of the entire set).
