PostgreSQL, also known as Postgres, is a powerful, open-source object-relational database management system (ORDBMS) renowned for its reliability, feature robustness, and performance. With over 35 years of active development, it has earned a strong reputation and is favored for its extensibility and SQL compliance. It supports transactions with ACID properties (atomicity, consistency, isolation, durability), automatically updatable and materialized views, triggers, foreign keys, and stored procedures.
PostgreSQL is supported across major operating systems, including Windows, Linux, macOS, FreeBSD, and OpenBSD. It handles diverse workloads, from single machines to data warehouses and web services with numerous concurrent users. Recent updates include versions 18.1, 17.7, 16.11, 15.15, 14.20, and 13.23, which address security vulnerabilities and bug fixes. The project continues to evolve with contributions from proprietary vendors, support companies, and open-source programmers, all under the free and open-source PostgreSQL License. Several upcoming community events are scheduled, such as PostgreSQL@SCaLE23x, FOSSASIA PGDay 2026, and PGConf India 2026.
