As a leader in Postgres innovation, EDB is proud to support and actively participate in the global PostgreSQL community. This commitment is reflected in our strong presence at PGDay.Belgium 2025, where four of our top technologists will be sharing critical insights into the future of PostgreSQL and the evolving needs of enterprise data infrastructure.
PostgreSQL has become the database of choice for a growing number of organizations—35% of enterprises are evaluating it for their next major workloads. EDB is at the forefront of this transformation, not only through our technology, but also through thought leadership and deep community engagement. PGConf.Belgium is an important moment to showcase the work our experts are doing to push Postgres forward in areas like performance, security, replication, and resilience.
Here’s a look at the talks from EDB’s Postgres leaders at PGDay.Belgium on May 6th:
Boriss Mejías: Live Fire with Logical Replication
Logical replication in PostgreSQL opens doors to powerful use cases, from near-zero downtime upgrades to geo-distributed architectures. But it’s not without its intricacies. Boriss Mejías, Postgres consultant and trainer at EDB, will take the audience through a dynamic, hands-on session that breaks and fixes replication on the fly. With a blend of theory and practical troubleshooting, Boriss will explore the full spectrum of logical replication—from best practices to real-world failure recovery. His session promises to be as engaging as it is educational, and a reminder that powerful tools require expert handling.
Gianni Ciolli: Unpacking the Why and What of WAL
The Write-Ahead Log (WAL) is a foundational component in PostgreSQL, yet its importance is often underappreciated outside of core contributors. Gianni Ciolli, Head of Global Support at EDB, brings clarity to the role WAL plays in crash recovery, hot backups, and replication. His talk will cover the origins of WAL and why its behavior is central to the reliability and efficiency of PostgreSQL in production. For architects and engineers building critical systems on Postgres, understanding WAL is non-negotiable—and Gianni makes it approachable and actionable.
Martín Marqués: Defending Backups Against Ransomware with Barman
In an era of increasing cybersecurity threats, database backups have become a new target for ransomware. Martín Marqués, senior database engineer at EDB, will present a compelling talk on how EDB’s Barman tool has been adapted to secure backups across diverse architectures, from cloud to on-prem. Drawing on real-world use cases, Martín will share strategies to harden backup infrastructure and highlight areas of ongoing innovation. For enterprises concerned about data resiliency, this talk offers critical insights and forward-looking solutions.
Our Commitment to the PostgreSQL Community
At EDB, our mission is to empower organizations to succeed with Postgres—from core OLTP systems to emerging analytical and AI workloads. PGDay.Belgium is one of many open source events where our experts engage with the community, share their work, and help guide the future of PostgreSQL.
We are proud of the depth and diversity of thought our team brings to this year’s conference. Whether it’s advancing replication, securing backups, or deepening the understanding of fundamental database mechanisms, EDB continues to lead with expertise and innovation.
