hi HN,While building Wolbarg (an open-source shared memory SDK for AI agents), I assumed PostgreSQL would be the obvious choice for memory storage.After benchmarking SQLite under realistic agent workloads, I was surprised by the results. For local-first and single-node deployments, SQLite handled far more than I expected while keeping the architecture much simpler.I wrote up the benchmarks, methodology, trade-offs, and where I still think PostgreSQL is the better choice.

Could you build this?
Yes This is a TypeScript wrapper around SQLite with vector extensions (like sqlite-vec) implementing standard memory read/write and search endpoints.
