PostgreSQL is a free object-relational database server (database management system), released under a flexible BSD-style license. It offers an alternative to other open-source database systems (such as MySQL and Firebird), as well as to proprietary systems such as Oracle, Sybase, IBM's DB2 and Microsoft SQL Server. Similar to other open-source projects such as Apache, Linux, and Mediawiki, PostgreSQL is not controlled by any single company, but relies on a global community of developers and companies to develop it.
