PostgreSQL is the world's most advanced open source database, with a global community of thousands of users, contributors, companies and organizations. Built on over 30 years of engineering, starting at the University of California, Berkeley, PostgreSQL has continued with an unmatched pace of development. PostgreSQL's mature feature set not only matches top proprietary database systems, but exceeds them in advanced database features, extensibility, security, and stability.

PostgreSQL uses the PostgreSQL License, a BSD-like "permissive" license. This OSI-certified license is widely appreciated as flexible and business-friendly, since it does not restrict the use of PostgreSQL with commercial and proprietary applications. Together with multi-company support and public ownership of the code, our license makes PostgreSQL very popular with vendors wanting to embed a database in their own products without fear of fees, vendor lock-in, or changes in licensing terms.
