Turso builds a Postgres frontend on its Rust SQLite engine

Sources: Turso blog, HN discussion
Summary: Turso described (2026-07-16) a plan to add Postgres compatibility to its Rust database engine, framed as "the LLVM of databases": one core with many database frontends. Postgres queries are parsed into a shared abstract syntax tree and compiled to Turso's VDBE bytecode, the same engine that runs its SQLite-compatible frontend with MVCC. The company calls the current code a foundation merged into the main repository, not a finished product, and lists goals including self-updating materialized views and file-based operation.
Why it matters: Reusing one bytecode core across SQLite and Postgres dialects is an unusual bet on a shared database VM, and it extends the SQLite and libSQL lineage into Postgres territory.
Follow-up: Watch for a runnable Postgres frontend, wire-protocol compatibility, and benchmarks against Postgres.
