I don't know why you want to

I understand that this is an important modification for abstracting (configuring) database connections, regardless of the engine chosen by the user.

@at146 sorry for the late reply, I was actually reconsidering this a bit

I usually migrate to a single env var for this, just for convenience (also most cloud's integrations expose that env variable, so it is easier to deploy)

you mean being able to do: DATABASE_URL=postgres+engine://host/db?

Exactly. Using DATABASE_URL is more of a semantic and practical convenience than something necessarily more technical. It removes the need for a SQLALCHEMY_DATABASE_URI environment and multiple lines defining POSTGRES_*.

I don't know about all the impacts involved, but apparently it wouldn't be a big problem. It would be interesting if a maintainer could clarify some doubts about this.

@at146 any specific reason why this modification wouldn't be useful?
