pgrust is a full rewrite of PostgreSQL in Rust that is wire- and SQL-compatible with Postgres and passes all 46,066 tests of the Postgres regression suite. It features a vectorized push-based JIT-compiled executor, thread-based concurrency, a query scheduler, and a built-in OOM killer, but is explicitly not production ready.

Use cases

• run a faster drop-in replacement for postgres
• test postgres workloads on a rust-rewritten database engine
• benchmark a database faster than postgres and clickhouse
• try postgres in the browser via wasm
• experiment with a jit-compiled vectorized query executor
• avoid postgres outages from runaway queries and oom kills

When to choose

• you want to experiment with a modern re-architecture of Postgres in Rust
• you need Postgres wire/SQL compatibility for testing or benchmarking
• you want to evaluate a vectorized JIT-compiled executor on Graviton4 hardware
• you want to run Postgres-compatible queries in a browser via WebAssembly

When to avoid

• you need a production database - the project explicitly says not to store data you care about in it
• you rely on PostgreSQL extensions or PL/Python, PL/Perl, or PL/Tcl
• you need stable behavior on non-Graviton4 hardware, since the JIT only targets Graviton4
• you need long-term stability - the project is early (v0.2) with many known bugs
