About EnterpriseDB (EDB)

EnterpriseDB, the original provider of pgLogical, today focuses on providing a data and AI platform that enables organizations to use Postgres for transactional, analytical, and AI workloads. EDB’s data-driven solutions enable companies to modernize legacy systems and data solos when leveraging open-source technologies.

About pgLogical (also known as pg logical replication)

Launched in 2015, pgLogical was created to address the need for advanced, flexible replication capabilities, enabling bi-directional data transfer, upgrades, and migrations. EDB continues to support and enhance pgLogical for PostgreSQL users.

pgLogical is an advanced logical replication extension for PostgreSQL, enabling seamless data replication between databases. It supports bi-directional replication, data migration, and high availability, making it ideal for distributed systems and upgrades. With minimal downtime and flexible configuration, pgLogical empowers businesses to achieve efficient, real-time data synchronization across environments.

About pgEdge Distributed Postgres

Beyond EDB Postgres, pgEdge Multi-Master and pgLogical both enhance PostgreSQL replication, but serve different needs. pgEdge Multi-Master enables active-active replication across multiple nodes, supporting global high availability and low latency. In contrast, pgLogical focuses on logical replication with flexible, bi-directional data transfer, making it ideal for upgrades and migrations, but less suited for multi-master workloads.

pgEdge and Postgresql pgLogical are both PostgreSQL-based replication solutions, but they serve different purposes:

  • pgLogical:

    • Developed by EDB, pgLogical provides advanced logical replication.

    • It supports uni- and bi-directional replication for migrations, upgrades, and selective data sharing.

    • Focuses on flexibility and minimal downtime.

  • pgEdge:

    • Fully standard postgres and fully open (source available)

    • Designed for multi-master, active-active replication across distributed nodes.

    • Enables global low-latency, high-availability systems by allowing all nodes to read and write simultaneously.

    • Built for edge computing and geographically distributed workloads
