True enterprise sovereignty is more approachable than ever, thanks to K8s-powered cloud-neutral PostgreSQL

Discussions on digital sovereignty are shifting from infrastructure to databases, driven by geopolitical pressures in Europe. Hyperscalers like Amazon and Microsoft are investing heavily to comply with new regulations, prompting organizations to reconsider their reliance on managed cloud services. Many enterprises are now viewing PostgreSQL as a portable, cloud-neutral foundation to ensure consistent behavior across various environments, leading to interest in Sovereign DBaaS. Gabriele Bartolini, VP and Chief Architect of Kubernetes at EDB, emphasizes that true sovereignty starts with the database and that portability enhances negotiating leverage and compliance. Bartolini warns that while managed cloud services offer convenience, they often sacrifice control. He notes that transitioning away from these services can provide long-term leverage, as evidenced by Microsoft's encouragement for customers to run self-managed PostgreSQL. The Operator Pattern in Kubernetes enables better database management and lifecycle control, with CloudNativePG exemplifying this approach. Bartolini asserts that owning hardware allows organizations to better manage costs, especially for resource-intensive AI workloads, and that moving to bare metal can significantly enhance performance. A cultural shift is necessary for success, with DBAs needing to adapt to cloud-native environments. Bartolini encourages DBAs to develop a broader understanding of Kubernetes to enhance collaboration across teams. He warns that the database team cannot drive change alone and must align with the entire infrastructure direction to avoid dependency on proprietary tools that limit independence and innovation.

PostgreSQL logical replication: How to replicate only the data that you need

Many organizations using PostgreSQL face challenges in replicating data across different logical databases while controlling shared information. PostgreSQL 15 introduces native logical replication with column-level and row-level filtering within publications, allowing precise control over data transfer between PostgreSQL databases. Logical replication operates on a publish-subscribe model, where the source database logs changes to the Write-Ahead Log (WAL) and applies publication filters to transmit only the relevant data to the target database. Two filtering modes are available: column-level filtering allows users to specify which columns to replicate, while row-level filtering uses WHERE clauses to determine which rows to include. Both filtering modes can be combined in a single publication. The SQL syntax for creating publications and subscriptions is consistent across various PostgreSQL environments, with specific configurations required for enabling logical replication. Use cases for logical replication include multi-tenant SaaS data isolation, regional data distribution for ecommerce, PCI DSS compliance in financial services, development and testing environments, and retail inventory management. Prerequisites for implementing logical replication include using PostgreSQL 15 or later, ensuring network connectivity, having a user with replication privileges, enabling logical replication on the source instance, and monitoring WAL retention. Logical replication has limitations, such as the need for a replica identity for UPDATE and DELETE operations, the non-replication of DDL changes and sequences, and potential performance overhead during initial synchronization and ongoing replication. After testing, it is advisable to clean up by removing replication resources to prevent unnecessary costs.

How to prevent updates on Windows 10 desktops

Organizations may pause or block Windows updates to maintain system stability and compatibility, particularly to avoid disruptions with legacy applications or customized environments, manage bandwidth consumption, and protect fortified Windows configurations. IT departments can disable updates using several methods: 1. Centralized patch management tools like WSUS or Microsoft Intune allow control over update deployment. 2. Configuring Group Policy settings can notify users of available updates without automatic installation. 3. Disabling the Windows Update service halts all future updates until re-enabled. 4. Setting a connection as metered can reduce automatic updates, though some critical updates may still download. In Windows 11, similar strategies apply, but organizations must consider the risks of blocking updates due to the end of regular security updates for Windows 10 and align their strategies with Microsoft's evolving update delivery methods.

Linux 7.0 Cuts PostgreSQL Performance in Half

An AWS engineer reported a significant drop in PostgreSQL throughput on Linux 7.0, with performance reduced to approximately half of its previous capability. Benchmark tests showed that the removal of the PREEMPT_NONE scheduling option was the main cause of this regression. On a 96-vCPU Graviton4 instance, throughput measured at just 0.51x compared to earlier kernel versions. Salvatore Dipietro from Amazon/AWS conducted benchmarking analysis of PostgreSQL 17, revealing that Linux 7.0 delivered only 0.51x the throughput of its predecessors. The root cause was traced to kernel commit 7dadeaa6e851, which eliminated PREEMPT_NONE as the default option, leading to increased contention due to the new PREEMPT_LAZY model. Profiling data indicated that 55% of CPU time is consumed by spinning in PostgreSQL’s spinlock, causing significant performance degradation. When a revert patch was applied, throughput rebounded to 1.94x the baseline. The decision to restrict preemption modes in Linux 7.0 aimed to address issues within the kernel's scheduling model. Dipietro proposed a patch to restore PREEMPT_NONE, but kernel developers suggested PostgreSQL adopt the rseq time slice extension instead. Database operators running PostgreSQL on Linux face potential performance reductions with the upgrade to Linux 7.0.

Don’t blame Windows 11 updates for every problem, Microsoft veteran says

Corporate clients often report to Microsoft that Windows updates disrupt their systems, particularly after Patch Tuesday. A 2026 report from Omnissa indicates that Windows environments experience more application crashes and forced shutdowns than macOS. However, Raymond Chen, a Windows expert, suggests that many systems are already compromised before updates are installed. Engineers at Microsoft frequently find that issues persist even after rolling back updates, and similar failures can occur on machines that haven't received the update yet. The actual triggers for system failures often stem from changes made by IT departments prior to updates, such as new drivers or configuration modifications. These changes may not show immediate issues until a reboot occurs during Patch Tuesday, revealing existing instability. Best practices for IT admins include controlled change management, validating drivers and policies before deployment, using staged rollouts, rebooting after major changes, and maintaining logging and monitoring systems. Microsoft conducts extensive testing of updates to ensure system security and stability, and delaying updates can increase risks.
