The Achievement

A milestone in database engineering

100%
Postgres regression tests passing
Complete compatibility with PostgreSQL behavior

What is pgrust?

  • 01
    Complete rewrite of PostgreSQL in Rust Reimplementing the world's most advanced open-source database
  • 02
    Full PostgreSQL compatibility Passes all official regression tests — identical behavior
  • 03
    Memory safety without garbage collection Rust's ownership model prevents common database bugs
  • 04
    Open source on GitHub github.com/malisper/pgrust — community-driven development

Why Rust Changes Everything

Traditional C Postgres
  • Manual memory management
  • Buffer overflow risks
  • Undefined behavior possible
  • Decades of accumulated code
pgrust (Rust) Future
  • Compile-time memory safety
  • Zero-cost abstractions
  • Thread safety guaranteed
  • Modern tooling & ecosystem
This demonstrates that even the most complex, battle-tested systems can be reimagined with modern language safety guarantees.
