In which areas do you expect PostgreSQL to grow most and how does your company contribute to and benefit from that growth?

We see the strongest growth for PostgreSQL in sovereign cloud environments. As the demand for digital independence in Europe rises, PostgreSQL has become the go-to open-source standard for organizations avoiding proprietary lock-ins. STACKIT contributes to this by offering a truly European managed service.

Our mission is to reduce dependency on non-European providers and protect data from external access or exploitation. Recent history has shown that reliance on foreign infrastructure can even hinder European legal entities. By providing PostgreSQL within our sovereign cloud, we enable users to leverage a world-class database while ensuring their data remains under European control. We benefit from this growth by attracting partners who prioritize security and self-determination.

What is your PostgreSQL centered product and what makes it unique?

STACKIT PostgreSQL Flexuniqueness lies in the perfect balance between enterprise simplicity and the uncompromising security of the companies of the Schwarz Group infrastructure.

We offer a "click-and-go" experience that automates deployment, scaling, and backups, removing the operational burden from developers. Unlike other providers, we back this simplicity with the stability of one of the largest retail groups in Europe, hosting everything in our own German and Austrian data centers. This ensures that high-performance database management remains easy to use while staying fully compliant and secure within a sovereign European framework.

What makes your company a great place to work?

Working at STACKIT means having a real impact on Europe’s digital future. We combine a dynamic start-up mentality with the stability of a major corporate group. Our culture is defined by openness and international collaboration, where diverse teams work together to solve complex challenges.

What truly sets us apart is our shared purpose: we are building the sovereign European cloud that our economy urgently needs. Our employees aren't just managing infrastructure; they are architects of digital independence. This mission, paired with a flexible and supportive environment, makes STACKIT a place where innovation and values go hand in hand.

Which PostgreSQL extension do you benefit from most, and why?

We see the most significant impact from pgvector and pgaudit.

pgvector is essential for our customers who are building modern AI applications. It allows them to store and search vector embeddings directly within their sovereign PostgreSQL instances, making it the cornerstone for secure, RAG-based (Retrieval-Augmented Generation) AI solutions in Europe.

On the other hand, pgaudit is vital for our mission of digital sovereignty and security. Since we serve highly regulated industries and public sectors, the detailed logging provided by pgaudit ensures the transparency and compliance our customers require. It allows them to fulfill strict auditing requirements while benefiting from the flexibility of a managed open-source database.

What feature is missing in PostgreSQL and how would it help if added?

The most significant missing feature in PostgreSQL core is Transparent Data Encryption (TDE). While there are workarounds at the filesystem or disk level, native TDE within the database engine would provide a much more granular and robust security layer.

As a provider focused on digital sovereignty and high-security standards, having TDE natively integrated would greatly simplify compliance for our customers in regulated industries. It would allow for encryption at rest that is independent of the underlying storage architecture, providing an extra layer of protection against unauthorized data access. Adding this would bring PostgreSQL on par with other enterprise database systems while maintaining its open-source integrity, making it even more attractive for sensitive European workloads.
