PostgreSQL is an open source relational database management system with a 24-year development history. It is free, robust, and popular. PostgreSQL supports many advanced features including user-defined types, functions, and extensions like PostGIS for geographic data. It can be used as a relational, object-relational, post-relational, key-value, document-centric, or big data database.
