Postgres is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads.

Postgres has earned a strong reputation for its proven architecture, reliability, data integrity, robust feature set, extensibility, and the dedication of the open source community behind the software to consistently deliver performant and innovative solutions. Postgres runs on all major operating systems, has been ACID-compliant since 2001, and has powerful add-ons such as the popular PostGIS geospatial database extender. It is no surprise that Postgres has become the open source relational database of choice for many people and organisations.


Postgres comes with many features aimed to help developers build applications, administrators to protect data integrity and build fault-tolerant environments, and help you manage your data no matter how big or small the dataset. In addition to being free and open source, Postgres is highly extensible.

Postgres features transactions with Atomicity, Consistency, Isolation, Durability (ACID) properties, automatically updatable viewsmaterialized viewstriggersforeign keys, and stored procedures.
