... is a waste of time and computing resources. Relational databases are optimized for specific usage scenarios. CAD systems and source code management systems are the archetypical examples of systems that are a bad fit and will kill the performance of a relational database. Of course 30 years later you can brute force it, but that doesn't make it a good idea. Git is far superior to rdb based systems for the day-to-day work and the analytics should be done from a ram-based object model.
