PostgreSQL vs EDB Postgres Advanced Server

PostgreSQL and EDB Postgres Advanced Server are two popular open-source and enterprise-level relational database management systems (RDBMS) used for a range of applications, from small websites to large-scale data analytics systems. In this article, we will compare these two systems and discuss their features, benefits, and limitations, to help you determine which one is the best fit for your needs.

PostgreSQL, also known as "Postgres," is an open-source RDBMS that has been in development since the 1980s. It is widely used for its reliability, robustness, and scalability, and has a large and active community of users and contributors.

PostgreSQL is known for its feature-rich SQL implementation, which includes support for advanced data types, such as arrays, hstore (a key-value store), and JSON/JSONB (binary JSON). It also supports advanced features, such as full-text search, geospatial data processing, and multi-version concurrency control (MVCC).

One of the key benefits of PostgreSQL is its strong community support, which provides a wealth of resources and tools for users, including a wealth of third-party extensions, plugins, and tools. Additionally, the open-source nature of the system makes it highly customizable and extensible, allowing users to tailor the system to meet their specific needs.

EDB Postgres Advanced Server, on the other hand, is a commercially-supported version of PostgreSQL that is maintained and supported by EnterpriseDB (EDB). EDB Postgres Advanced Server is designed to provide a range of advanced features and capabilities that are not available in the open-source version of PostgreSQL, including support for Oracle compatibility, advanced security features, and management tools.

One of the key benefits of EDB Postgres Advanced Server is its support for Oracle compatibility, which makes it an ideal choice for organizations looking to migrate from Oracle to a more cost-effective and open-source solution. The system provides a range of tools and features to make the migration process smoother and more straightforward, including support for Oracle-compatible SQL, PL/SQL, and stored procedures.

Another benefit of EDB Postgres Advanced Server is its advanced security features, which provide a range of tools and capabilities to help organizations secure their databases and protect sensitive data. The system provides features such as advanced auditing, data masking, and data encryption, to help organizations meet their security and compliance requirements.

Despite its many benefits, EDB Postgres Advanced Server is a commercial product, and as such, it comes with a licensing fee. Additionally, the tool may not be as customizable as the open-source version of PostgreSQL, as it is designed to provide a turn-key solution for advanced features and capabilities.


Both PostgreSQL and EDB Postgres Advanced Server are powerful and flexible relational database management systems that are well suited for a range of applications. If you are looking for a highly customizable, open-source solution with a strong community, then PostgreSQL may be the best choice for you. If, on the other hand, you are looking for a commercially-supported solution with advanced features and capabilities, then EDB Postgres Advanced Server may be the better choice. Ultimately, the best choice will depend on your specific needs and requirements, and it is important to carefully consider these factors when making your decision.
