GoKawiilpgrust
A Postgres rewrite in Rust.
pgrust targets compatibility with Postgres 18.3 and matches Postgres's expected output across more than 46,000 regression queries.
pgrust is disk compatible with Postgres and can boot from an existing Postgres 18.3 data directory.
The goal is to make Postgres easier to change from the inside: keep the behavior Postgres-shaped, keep the real Postgres tests as the oracle, and use Rust plus AI-assisted programming to explore deeper server changes.
Status
pgrust is not production-ready yet. It is not performance optimized yet.
Existing Postgres extensions and procedural language extensions such as PL/Python, PL/Perl, and PL/Tcl are not generally compatible yet. Some bundled contrib modules are already ported, and more compatibility may be possible over time.
