The World's Most Advanced Open Source Relational Database

PostgreSQL, also known as Postgres, is a powerful, open-source object-relational database system. It has earned a strong reputation for its proven architecture, reliability, data integrity, robust feature set, and extensibility

Advanced Data Types

See built-in data types and custom types and domains for modeling OOP in the database itself.


One of PostgreSQL's hallmark features is its extensibility. Developers can define their own data types, custom functions, and even write code in different programming languages without recompiling your database.

PostgreSQL comes with powerful full-text search capabilities that allow you to search through text-heavy data types easily. This feature is highly customizable and efficient, making it ideal for applications requiring complex search functionalities.

Concurrency and Multiversion Concurrency Control (MVCC)

PostgreSQL uses MVCC to handle concurrent data access. This system allows for efficient and safe concurrent reads and writes, enhancing performance without sacrificing data integrity.

Robust Transaction and ACID Compliance

PostgreSQL is fully ACID-compliant (Atomicity, Consistency, Isolation, Durability), ensuring that your database transactions are processed reliably. This guarantees that your data remains consistent and safe even in the event of power failures or crashes.

Advanced Indexing

PostgreSQL offers several indexing techniques, including B-tree, Hash, GiST, SP-GiST, GIN, and BRIN indexes. This range of indexing options allows for fast data retrieval and can be optimized based on your specific use case.


PostgreSQL provides a comprehensive suite of security features, including strong authentication mechanisms (such as SCRAM-SHA-256), role-based access control, row-level security, and data encryption. These features help protect sensitive data and ensure that only authorized users can access specific data sets.

Scalability and Replication

With support for synchronous and asynchronous replication, PostgreSQL can scale horizontally to accommodate read-heavy workloads. This, combined with features like partitioning, ensures that PostgreSQL can handle large datasets and high throughput applications.

Extensive Ecosystem

The PostgreSQL ecosystem includes a wide range of tools and extensions, such as PostGIS for geographic information systems, various foreign data wrappers for integrating with other databases, and tools for performance monitoring and tuning.

PostgreSQL's advanced features and flexibility make it an excellent choice for developers looking for a reliable, scalable, and powerful database solution. Whether you're building simple applications or complex systems requiring extensive data analysis, PostgreSQL provides the tools and capabilities to meet your needs.
