Thanks for trying to help me @Kaniz Fatma​ .

My question was not to learn how to set up mlflow with postgres. But, to learn what additional advantage would using an sql-alchemy database like postgres would have, instead of storing all the metadata to files. that is, what advantage would I have, if I use an sql-alchemy for backend and not use one. please note that, the mlflow server will not be in '--artifacts-only' mode?
