The World’s Most Advanced Open Source Database
PostgreSQL is a powerful, open source, ACID compliant object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance. It uses an extremely liberal open source license, making it free to use and distribute – unlimited & forever!
PostgreSQL (or Postgres) began its life in 1986 as POSTGRES, a research project of the University of California at Berkeley, led by highly influential database researcher Michael Stonebraker.
