PostgreSQL is a powerful, advanced, fast, and open source object-relational database system based on POSTGRES, Version 4.2.

PostgreSQL supports a large part of the SQL standard with many modern features such as complex queries, triggers, updatable views, transactional integrity, multiversion concurrency control, etc. Additionally, PostgreSQL can be extended by the user by adding new data types, functions operators, aggregate functions, index methods, and procedural languages.
