[The content under each section is a suggestion. Feel free to change it] PostgreSQL, in its traditional form, is not inherently a distributed database system. It's primarily designed as a single-node relational database management system (RDBMS). However, with the introduction of features like Foreign Data Wrappers (FDWs), logical replication, and streaming replication, PostgreSQL has gained capabilities that enable it to function in distributed environments to some extent.

While these features allow PostgreSQL to interact with data sources external to the database itself, such as other PostgreSQL instances, databases of different types, or even non-database sources, they don't inherently transform PostgreSQL into a fully distributed database system. True distributed database systems are specifically engineered to distribute data across multiple nodes, with built-in mechanisms for replication, partitioning, and coordination among nodes to ensure consistency, fault tolerance, and scalability.

That said, PostgreSQL can be part of a distributed architecture when combined with other technologies or when used in conjunction with distributed database extensions or solutions like EDB Postgres Distributed (PGD). These extensions provide the necessary functionalities to transform PostgreSQL into a distributed database system, allowing organizations to scale horizontally across multiple nodes, achieve high availability, and distribute data across geographically dispersed locations while leveraging PostgreSQL's rich feature set and SQL compatibility.

Distributed PostgreSQL, also known as EDB Postgres Distributed or PGD, is a powerful extension of EnterpriseDB's PostgreSQL database management system. It leverages the flexibility and robustness of PostgreSQL while introducing innovative features to address the complexities of modern data management.

At its core, Distributed PostgreSQL empowers organizations to scale their database infrastructure horizontally across multiple nodes, both on-premises and in the cloud. By distributing data and workload across a cluster of servers, organizations can achieve unparalleled scalability, high availability, and fault tolerance, ensuring uninterrupted access to critical data even in the face of hardware failures or sudden spikes in demand.

EDB Postgres Distributed (PGD) provides multi-master replication and data distribution with advanced conflict management, data-loss protection, and throughput up to 5X faster than native logical replication
