PostgreSQL, also known as Postgres, is a free and open-source relational database management system emphasizing extensibility and SQL compliance. Originally named POSTGRES at UC Berkeley in 1986, PostgreSQL is now developed by a worldwide team of volunteers known as the PostgreSQL Global Development Group.
It supports advanced data types (JSONB, arrays, geometric, range), full-text search, partitioning, replication, and is the de facto choice for modern application backends.
The world's most advanced open-source relational database. ACID-compliant, extensible, battle-tested.
