About PostgreSQL

PostgreSQL is a powerful, open-source object-relational database management system known for its reliability, performance, extensibility, and standards compliance. With over 30 years of active development, PostgreSQL is widely used by organizations of all sizes for mission-critical applications.

PostgreSQL supports advanced SQL features, complex queries, indexing, full-text search, JSON and JSONB data types, geospatial data, and extensibility through custom functions and extensions. Its robust architecture makes it suitable for high-transaction workloads, analytics, and modern cloud-native applications.

As a vendor-neutral and open-source database, PostgreSQL allows organizations to avoid vendor lock-in while benefiting from a strong global community, regular updates, and proven stability. PostgreSQL runs on all major operating systems and is supported across on-premises, cloud, and hybrid environments.

PostgreSQL is trusted by leading companies worldwide for applications requiring data integrity, high availability, scalability, and security.
