⭐ 540 💬 331 👤 soheilpro 🔗 Discuss on HN
PostgreSQL 19 is expected to ship later than usual because several major features were reverted late in the beta cycle. The delay stems from a surge in bug reports, many discovered with the help of LLMs, which has increased the workload for fixing and reviewing code across current and older releases. The project’s focus on quality is causing the postponement, though the long-term impact of uncovering decades of latent bugs remains uncertain.
