PostgreSQL History	Postgres Notion	Jul 19, 2023	Alan Jo	Alan Jo	Jul 19, 2023		PostgreSQL the database was derived from the POSTGRES Project, a package written at the University of California at Berkeley in 1986. This package included a query language called "PostQUEL". In 1994, Postgres95 was built on top of POSTGRES code, adding an SQL language interpreter as a replacement for PostQUEL.Eventually, Postgres95 was renamed to PostgreSQL to reflect the SQL query capability. > [Database \| Supabase Docs](https://supabase.com/docs/guides/database/overview)	f17a307eec7e4f7f9fd2191784f2c856

Jul 19, 2023

PostgreSQL the database was derived from the POSTGRES Project, a package written at the University of California at Berkeley in 1986. This package included a query language called "PostQUEL". In 1994, Postgres95 was built on top of POSTGRES code, adding an SQL language interpreter as a replacement for PostQUEL.Eventually, Postgres95 was renamed to PostgreSQL to reflect the SQL query capability. > [Database | Supabase Docs](https://supabase.com/docs/guides/database/overview)
