Babelfish for PostgreSQL is an open-source project that adds a Microsoft SQL Server-compatible end-point to PostgreSQL. Babelfish allows PostgreSQL to understand T-SQL, SQL Server’s proprietary SQL dialect, and supports the TDS communication protocol, so applications originally written for SQL Server may work with PostgreSQL with fewer code changes and without changing database drivers.

This repository contains the release distributions for the Babelfish project. Each distribution contains the source code for Babelfish as well as the corresponding PostgreSQL version and some prerequisite software.

Additional Github repositories contain:

• Babelfish project source code.
• PostgreSQL source code that has been modified for use with Babelfish.
• The Babelfish website source and build information.
• Babelfish Compass is a tool that helps you evaluate Babelfish compatibility for your database. Source code and documentation are available from the Github repo.

The Babelfish project welcomes contributions to the project source code and the website - review the Guidelines for contributing code or documentation to learn more. We also invite your feedback:

• about new content,
• to remove or report inaccuracies,
• to fill information gaps,
• to fix typos or grammatical errors, and
• to improve clarity.

Babelfish for PostgreSQL is available as open-source software and can be downloaded from Github for free under the terms of the Apache 2.0 license and the PostgreSQL license.

Babelfish would not be possible without the hard work and dedication of the people who have contributed to PostgreSQL. Everyone involved in the development of PostgreSQL has our gratitude.
