Wire-protocol ADBC driver

PostgreSQLv0.3.8

Native Frontend/Backend v3, no libpq

Database: PostgreSQL
Protocol: FEBE v3
Load name: "arrowfebe"
Version: v0.3.8
Platforms: Linux (x64) · Windows (x64)

Overview

This is a pure-native ADBC driver for PostgreSQL that speaks the Frontend/Backend (FEBE) wire protocol v3 directly over TCP/TLS. It supports PostgreSQL 12 to 17 and PostgreSQL-compatible services, does not use libpq, and relies on OpenSSL as its primary runtime dependency.

What it does differently

No libpq in the picture

The FEBE v3 protocol is implemented in the driver, so there is nothing to install, version-match or ship alongside your application.

NUMERIC without the string detour

PostgreSQL NUMERIC maps directly to Arrow decimal128 / decimal256 — faster than a text round-trip and lossless where text is not.

PostGIS ready

Interval types and PostGIS EWKB geometry are mapped natively, so spatial columns arrive usable rather than opaque.

Straight into Arrow buffers

Results decode into Arrow column buffers with no intermediate row objects on the way.

Authentication

SCRAM-SHA-256, with channel binding
MD5 and cleartext passwords
GSSAPI / Kerberos and Windows SSPI
GSS transport encryption via gssencmode

Connect from your language

The driver loads by name across every ADBC client. Pick your language:

query.py

import adbc_driver_manager.dbapi as dbapi

with dbapi.connect(driver="arrowfebe",
                   db_kwargs={"uri": "postgresql://dbuser:<password>@host:5432/appdb?sslmode=require"}) as conn:
    cur = conn.cursor()
    cur.execute("SELECT * FROM public.orders")
    table = cur.fetch_arrow_table()   # ready as Arrow

Install the PostgreSQL driver

install.sh

curl -fsSL https://raw.githubusercontent.com/arpe-io/adbc-drivers/main/install.sh \
  | sh -s -- arrowfebe --license /path/to/your.lic
