Beyond the commit log
The long-term success of open‑source software depends equally on the sharing of knowledge, active collaboration, and visible participation in the communities that guide its evolution. Mailing‑list discussions, conference talks, technical writing, and mentoring all play a role in shaping how a project grows and who it serves.
Alongside its upstream engineering contributions, Fujitsu has made sustained investments in these less visible but equally critical dimensions of the PostgreSQL ecosystem. Through openly accessible technical resources, dedicated knowledge platforms, and active involvement in conferences and user groups around the world, Fujitsu helps turn individual engineering experience into collective community progress.
PostgreSQL Blog offers real-world insights from the engineers building it
One of the most visible ways Fujitsu shares this expertise with the broader community is through the PostgreSQL Blog to offer direct insights from engineers.
The blog brings together deep technical exploration and real‑world operational insight, covering topics that matter most to teams running PostgreSQL at scale, with posts dive into logical replication internals and zero‑downtime upgrades, practical guidance on publication filtering and WAL behavior, and long‑term performance evolution within PostgreSQL’s Query Optimizer. Alongside these core database topics, the blog also addresses broader enterprise concerns such as data sovereignty, hybrid and on‑prem continuity, security and compliance frameworks, and the emerging role of AI and Retrieval‑Augmented Generation (RAG) within PostgreSQL. Together, these articles reflect a focus on production‑grade PostgreSQL—where resilience, correctness, and long-term maintainability are as important as new features.
On a more personal note, the blog section also hosts A Day in the Life profiles of Fujitsu's engineers, with candid accounts of how a typical working day is structured around upstream. And for teams migrating from legacy databases, Tim Steward's guide What I wish I had when learning PostgreSQL after Oracle is a valuable resource for architects navigating the transition to open-source stacks.
PostgreSQL Zone is built by engineers, free for everyone
Complementing these knowledge‑sharing efforts, we also publish the PostgreSQL Zone , a platform designed to make deep, practitioner‑level PostgreSQL knowledge openly accessible to everyone.
Beyond conference stages, Fujitsu maintains this hub of deep technical content that is free and openly accessible. This is where the team's engineering insights become public resources.
Recent highlights include Peter Smith's definitive guide on CREATE PUBLICATION syntax and the logical replication of stored generated columns (a PostgreSQL 18 highlight), Nikhil Bayawat's discussion of how to leverage PostgreSQL and Scaled Agile Framework for enterprise success, and Gary Evans's TPC-H benchmark analysis using DBT3 —a practical reference for teams evaluating PostgreSQL's analytical performance.
Fujitsu Enterprise Postgres: Where upstream meets production
All of the upstream work described above flows into Fujitsu Enterprise Postgres —Fujitsu's enterprise distribution of PostgreSQL. Fujitsu Enterprise Postgres extends the community edition with features that matter most in production environments:
- Advanced security controls and compliance reporting
- High availability and disaster recovery tooling
- Performance optimization and operational monitoring
- In-Memory Columnar Index (developed by Fujitsu Labs as Vertical Clustered Index) for analytical workloads
- Vector search capabilities for RAG-based AI applications
Critically, Fujitsu Enterprise Postgres maintains full alignment with upstream PostgreSQL. Customers do not inherit a fork that diverges from the community; they inherit all upstream improvements plus Fujitsu's enterprise additions. The IBM Redbooks guide on Fujitsu Enterprise Postgres on IBM systems, co-authored by Fujitsu engineers, is one public illustration of this integration at scale.
A global voice in conferences and community leadership
Code is only half the story. The other half is the community work that shapes PostgreSQL's direction before a line of code is written—the mailing-list debates, the conference presentations, the hallway conversations at hackfests that turn a rough idea into a committed patch.

Fujitsu: In it for the long game
The evolution of PostgreSQL is a story of continuous collaboration across organizations, time zones, and release cycles. Fujitsu's role in that story is long, substantive, and ongoing.
From the first features contributed to PostgreSQL 8.0 to the conflict resolution engine in PostgreSQL 18; from Rajni Baliyan's early talks at PGDay Australia to Peter Smith's row-filter patches, Fujitsu has consistently put engineering resource where it matters most: in the upstream project that the world depends on.
As PostgreSQL continues to grow into AI-era workloads, multi-master distributed systems, and regulated enterprise environments, that commitment will remain central to the project's success.
