Very nice to hear, I will follow your project.
One of the projects I was thinking about is financial systems used by government actors such as correctional services. For these customers there’s strong legal requirements for data handling so a database super user with full access is a big no-no even for the most trusted developers internally.
We completely understand. We want to have the ability for Mathesar to gracefully handle DB users with different permissions (i.e. we'd disable features in the UI based on the permissions of the DB user set up during installation), but we couldn't get that done in time for launch. We'll continue working on this.
