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.
Sparta famously discouraged precious-metal coinage (using heavy iron money internally), but in later Hellenistic and Roman periods Spartans did strike limited, rare coins — notably royal silver tetradrachms (Areus, Cleomenes, Nabis), Achaean League issues, and Roman provincial bronzes. The article surveys these types and their historical contexts, explaining why genuine Spartan coins are scarce and significant to collectors and historians.
