Suppose I'm working on a new feature branch and I run a bunch of migrations and add new data. Then I need to go make a bug fix on the master branch. Using Stellar, I could just take a snapshot before starting my feature branch, restore the DB state, do my bug fix, then go back to the DB as it was in my feature branch. I haven't tried Stellar yet, but this seems like a scenario where it would be useful. (And definitely not supported through Postgres transactions.)

You could use schemas or multiple databases for that.

True. Although then you would have to worry about changing your DB configuration whenever you change branches. You'd also have to make a copy of your database manually any time you want to start modifying it. Stellar seems like an easier solution.
