PostgreSQL History
PostgreSQL is currently the most advanced open-source database available in the world. It was started in 1986 to overcome the problems of the contemporary database system. It was created by a computer science professor named Michael Stonebraker at UCB and was originally called Postgres, as it was started as a follow-up project and a post-Ingres project.
