It also allows you to host multiple databases in the same instance which is what I want for a lot of my hobby apps as they don't really have a lot of data.
The service exposes a standard database URL and so far I have been able to use standard Postgres tools for everything I've wanted to do with the database. You can even just cut and paste a string to connect with
The documentation for migrating from Render to Heroku is excellent and worked just as advertised.

DATABASE_URL environment variable with the new URL from Render, restarted my dynos and every application I had worked perfectly.
The only issue I had was in my local setup where I needed to use the
pg_restore from a matching version which I needed to specify the exact
