Support for MongoDB / other databases.

I've been using Firebase and Firestore for a while but it's inflexibility for more advanced queries made me look for alternatives and thats how I found out about Supabase with it's PostgreSQL database. While Supabase requires a bit more tinkering to setup different things (at the moment at least), I certainly appreciate the flexible SQL queries it allows. However, the strict schema of SQL databases makes it a bit clunky for projects with multiple developers since the schema should be kept in sync all the time.

As mentioned earlier, Firestore NoSQL is not flexible with certain queries like range-queries on different fields, unlike MongoDB which does allow more flexible queries.
