pgrust is a Rust rewrite of PostgreSQL targeting compatibility with Postgres 18.3 — disk-compatible, boots from existing data directories, and matched Postgres's expected output across >46,000 regression queries and now reportedly passes 100% of the regression suite. The newer implementation uses a thread-per-connection model and claims large performance gains (≈50% faster on transactional workloads, ~300× faster on analytical workloads) but is experimental, not yet production-ready, and lacks full extension compatibility.

The article explains that mini‑PCs with unified (soldered) memory can load large LLMs that discrete GPUs cannot because the model can live in the shared RAM, but they are much slower at generation because memory bandwidth — not capacity — determines token throughput. It also notes prompt processing (prefill) is compute‑bound on these devices, MoE models can avoid the bandwidth penalty, and NPUs rarely change the practical bottleneck.
