pqi-native: Native (pure-Haskell) adapter for pqi

[ database, library, mit, postgresql ] [ Propose Tags ] [ Report a vulnerability ]

A pqi adapter that speaks the PostgreSQL frontend/backend wire protocol directly, with no dependency on the C libpq library. The transport layer (framing, message serialization/deserialization, socket I/O) is isolated in an internal transport sub-library built on ptr-poker and ptr-peeker; the public library is an abstraction over it that implements the pqi capability classes.

pqi-native

Hackage Continuous Haddock

A pure-Haskell pqi adapter that speaks the PostgreSQL frontend/backend wire protocol directly — no dependency on the C libpq library.

pqi-native is an LLM-generated port of the PostgreSQL C client library, libpq. The upstream libpq source is the direct reference for the implementation.

Fidelity goal

The goal is byte-identical output to libpq for every protocol-derived value — error message strings, notice text, result status, field metadata, cell data, and all structured error fields. Fidelity is continuously enforced by pqi-conformance, which runs every operation on both this adapter and a direct postgresql-libpq reference connection against the same database and asserts exact equality.

Status

All classes are implemented. Verified against the postgresql-libpq reference via the conformance differential suite.

Authentication: trust, MD5, and SCRAM-SHA-256 are implemented. SCRAM is verified against a password-auth PostgreSQL 17 container (which defaults to scram-sha-256).
