I'm building a programmable PostgreSQL proxy in Rust. The idea is to make it easy to consume the replication stream so it can do query caching with automatic invalidation, and so that people can build custom partitioning, caching, or real-time features on top of PostgreSQL. The proxy part is implemented, but there's still a lot of work to add the replication and caching features, and to test and polish everything to production standards - databases are serious business. The project is on github here: https://github.com/riverdb/riverdb

I don't even know if this is something people would want or pay for if I completed it. And then there's the task of marketing/selling it, which is way outside of my skillset. Should I just give up (grow up?) and get a job? Is it worth pressing on here? I'm not consuming my savings, but neither am I making financial progress, and I'm not getting any younger.
