Since then developers and volunteers around the world have maintained the software as The PostgreSQL Global Development Group. The first PostgreSQL release formed version 6.0 on January 29, 1997. The online presence at the website began on October 22, 1996. In 1996, the project was renamed to PostgreSQL to reflect its support for SQL.

Mikheev, work began to stabilize the code inherited from Berkeley. With the participation of Bruce Momjian and Vadim B. On July 8, 1996, Marc Fournier at Hub.org Networking Services provided the first non-university development server for the open-source development effort.

Version 1.0 of Postgres95 was announced on September 5, 1995, with a more liberal license that enabled the software to be freely modifiable. Yu and Chen announced the first version (0.01) to beta testers on May 5, 1995. The monitor console was also replaced by psql. In 1994, Berkeley graduate students Andrew Yu and Jolly Chen replaced the POSTQUEL query language interpreter with one for the SQL query language, creating Postgres95. At the time, POSTGRES used an Ingres-influenced POSTQUEL query language interpreter, which could be interactively used with a console application named monitor. Berkeley released POSTGRES under an MIT License variant, which enabled other developers to use the code for any use. After releasing version 4.2 on June 30, 1994 – primarily a cleanup – the project ended. By 1993, the number of users began to overwhelm the project with requests for support and features. Version 3, released in 1991, again re-wrote the rules system, and added support for multiple storage managers and an improved query engine. The team released version 1 to a small number of users in June 1989, followed by version 2 with a re-written rules system in June 1990. Starting in 1986, published papers described the basis of the system, and a prototype version was shown at the 1988 ACM SIGMOD Conference. POSTGRES used many of the ideas of Ingres, but not its code. In POSTGRES, the database understood relationships, and could retrieve information in related tables in a natural way using rules. These features included the ability to define types and to fully describe relationships – something used widely, but maintained entirely by the user. The new project, POSTGRES, aimed to add the fewest features needed to completely support data types. He won the Turing Award in 2014 for these and other projects, and techniques pioneered in them. He returned to Berkeley in 1985, and began a post-Ingres project to address the problems with contemporary database systems that had become increasingly clear during the early 1980s. In 1982, the leader of the Ingres team, Michael Stonebraker, left Berkeley to make a proprietary version of Ingres. PostgreSQL evolved from the Ingres project at the University of California, Berkeley. It was the default database for macOS Server and is also available for Linux, FreeBSD, OpenBSD, and Windows. It is designed to handle a range of workloads, from single machines to data warehouses or web services with many concurrent users. PostgreSQL features transactions with atomicity, consistency, isolation, durability ( ACID) properties, automatically updatable views, materialized views, triggers, foreign keys, and stored procedures. After a review in 2007, the development team decided to keep the name PostgreSQL and the alias Postgres. It was originally named POSTGRES, referring to its origins as a successor to the Ingres database developed at the University of California, Berkeley.
