Meet PostgreSQL

PostgreSQL is an open-source relational database for applications that need structured data, SQL queries, and dependable transactions. Developers use it to store business records, model relationships, and enforce data integrity with constraints and foreign keys. It also supports JSON documents, full-text search, and a broad range of indexing options, allowing different data types to work together within one database.

Administrators can use replication, backups, and point-in-time recovery to build resilient deployments. PostgreSQL runs on major operating systems and can be extended with custom data types, functions, and programming languages. Extensions such as PostGIS add specialized capabilities for geographic data. Its combination of transactional foundations and extensibility makes it useful for web applications, internal systems, and services with evolving data requirements.
