PostgreSQL is an Object-Relational Database Management System (ORDBMS) that has been developed in various forms since 1977. It began as a project named Ingres at the University of California at Berkeley. Ingres itself was later developed commercially by Relational Technologies/Ingres Corporation.
PostgreSQL is an open source project. Open source by definition means that you can obtain the source code, use the program, and modify it freely without the confines of proprietary software. In the database world, open source means that you have honest access to benchmarking numbers and performance statistics, which companies such as Oracle prohibit. Open source also means that you are free to modify PostgreSQL to fit your particular needs.
