The Apache Arrow team is pleased to announce the 0.1.0 release of
the Apache Arrow Flight SQL adapter for PostgreSQL. This includes
[**60 commits**][commits] from [**1 distinct
contributors**][contributors].

The release notes below are not exhaustive and only expose selected
highlights of the release. Many other bug fixes and improvements have
been made: we refer you to [the complete release notes][release-note].

## What is Apache Arrow Flight SQL adapter for PostgreSQL?

Apache Arrow Flight SQL adapter for PostgreSQL is a PostgreSQL
extension that adds an [Apache Arrow Flight
SQL](https://arrow.apache.org/docs/format/FlightSql.html) endpoint to
PostgreSQL.

Apache Arrow Flight SQL is a protocol to use [Apache Arrow
format](https://arrow.apache.org/docs/format/Columnar.html) to
interact with SQL databases. You can use Apache Arrow Flight SQL
instead of [the PostgreSQL wire
protocol](https://www.postgresql.org/docs/current/protocol.html) to
interact with PostgreSQL by Apache Arrow Flight SQL adapter for
PostgreSQL.

Apache Arrow format is designed for fast typed table data exchange. If
you want to get large data by `SELECT` or `INSERT`/`UPDATE` large
data, Apache Arrow Flight SQL will be faster than the PostgreSQL wire
protocol.

## Release Highlights

This is the initial release!

This includes the following basic features. Other features will be
implemented in the future releases.

* Literal `SELECT`/`INSERT`/`UPDATE`/`DELETE`
* Prepared `SELECT`/`INSERT`/`UPDATE`/`DELETE`
* `password`/`trust` authentications
* TLS connection
* Integer family types
* Floating point family types
* Text family types
* Binary family types
* Timestamp with time zone type

Packages for Debian GNU/Linux bookworm and Ubuntu 22.04 are available.
