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.
