Postgres rewritten in Rust, now passing 100% of the Postgres regression tests

What commenters are saying

Commenters split into two camps: those debating the role of AI in rewrites and those questioning whether passing regression tests alone guarantees robustness. Some argued that AI-generated code quality depends on the engineer driving it, not just the model. Others countered that production scars and real-world use matter more than any test suite. A subthread noted that even well-written tests can fail to capture edge cases or new bugs introduced by a translation.
