Thinking About Building a New Open-Source Database — Looking for Problems to Solve & Passionate People to Team Up

I’m a big fan of PostgreSQL and recently started thinking about building a new database system as a side project. I know creating a database is a huge challenge, and I’m still learning, but I really like the idea. If a few passionate people team up together, I believe we can build something interesting. I’d love to know: What struggles do you face with current databases? What features are missing in existing systems? What problems do you wish databases solved better? Performance? Scaling? RAM usage? Replication? Developer experience? Your feedback and ideas would really help. Or shorter and more Reddit-style: Title What problems do you face with existing databases? Content I’m thinking about creating a new database project because I really enjoy working with PostgreSQL. I know it’s a huge challenge, but I like the idea and want to learn deeply by building something. If a few passionate developers team up, maybe we can create something interesting. What problems or frustrations do you currently face with databases? What would you improve if you could design your own database? I’m deeply interested in backend architecture, distributed systems, and database engineering. Previously, I built a backend framework in Go called KVolt, which gave me strong experience in scalability, API architecture, performance optimization, and system design. Recently, I started exploring a bigger challenge: I’m a big fan of PostgreSQL, but I believe there’s still room for innovation in areas like: Performance Scalability Distributed systems Replication Memory optimization Developer experience Modern architecture design I know database engineering is one of the hardest areas in software development, and that’s exactly why it interests me. I’m also looking for a few passionate developers, backend engineers, and system-level programmers who genuinely enjoy solving hard engineering problems and would like to team up on this open-source journey. I’d love to hear from the community: What struggl
