It has a strong reputation for reliability, stability, and data integrity.

PostgreSQL is actually pronounced as post-gress-QL and the most interesting thing about it is that it is maintained and developed by a worldwide team of volunteers. This means that it is not under the control of any big private corporation and its code is open-source.

PostgreSQL was first created in 1986 at the University College Birmingham by Michael Stonebraker, who was a computer science professor there. It was first started as a follow-up project to Ingres, which is now owned by Computer Associates.

PostgreSQL can be run on all the major operating systems like Windows, Linux, and Unix. It has support for images, video, and text. There are also programming interfaces for C, C++, Java, Perl, Ruby, Tcl, and Open Database Connectivity.

It supports a large part of the SQL standard and its features include complex SQL queries, SQL sub-selects, trigger, foreign keys, views, transactions, multi-version concurrency control, streaming replication, and Hot Standby. The official documentation of PostgreSQL can be checked by anyone and users can also add new features like data types, functions, operators, aggregate functions, and index methods.
