Google Pushes AI for PostgreSQL Development

Google is integrating artificial intelligence into PostgreSQL engineering while ensuring engineers remain responsible for their code contributions. This initiative aims to improve productivity and streamline processes, particularly in version upgrades, replication behavior, and production recovery. Sailesh Krishnamurthy, Google Cloud's VP of Databases, emphasized the importance of human oversight in this AI-driven approach. Between July and December 2025, Google's PostgreSQL engineering focused on logical replication, improvements to pg_upgrade, and upstream bug fixes. Logical replication allows selective database change transfers, which is beneficial for migrations and upgrades. The roadmap includes Automatic Conflict Detection and logical replication of sequences to minimize manual synchronization issues. Enterprise teams are particularly interested in these developments due to the challenges posed by write collisions and misaligned sequence values. The demand for PostgreSQL services at Google is increasing due to migration needs from Oracle and SQL Server. Recent data shows PostgreSQL's rising popularity, ranking fourth in the DB-Engines ranking and gaining 8.37 points year over year, while its competitors experienced declines.

Beware of Activating Them: 5 Android App Permissions That Pose a Threat to Your Data

Android applications often request various permissions upon installation, including access to the camera, microphone, contacts, messages, and accessibility features. Users frequently accept these requests without hesitation, which can compromise their device's privacy and security. Certain permissions, if granted to malicious apps, can enable monitoring of user activity, audio recording, location tracking, or unauthorized app installations. Five Android app permissions that require careful consideration before granting include: 1. Accessibility Services: Can allow untrusted apps to monitor screen content, read messages, track keystrokes, and perform actions on behalf of the user. 2. Display Over Other Apps: Allows apps to overlay content on other apps, which can be exploited by malicious apps to create deceptive interfaces. 3. Install Unknown Apps: Permits apps to install software from outside the Google Play Store, increasing the risk of malware. 4. Usage Data Access: Enables apps to monitor usage patterns, which can be used for targeted advertising or sold to data brokers. 5. Access to Contacts and Messages (SMS): Sensitive information can be intercepted by malicious apps, posing risks to account security. It is crucial to grant permissions that align with an app's intended function and to be cautious of unnecessary access.

Windows 11 Clients: The Group Policy Editors gpedit.msc and GPMC are broken

The Group Policy Editors gpedit.msc and gpmc from the RSAT tools are experiencing functionality issues in Windows 11 due to a bug that causes an overflow error, resulting in incorrect configurations being saved. This issue was first reported by Mark Heitbrink to Microsoft in March 2026, but he has not received feedback. The bug appears to be unique to Windows 11 clients, as tests on Windows Server did not show the problem. Mark documented the bug with submission number VULN-180447 and case number 111952. He described how to reproduce the issue involving the group policy "Delay Foreground download from http" and the decimal value "4294967295," which gets altered to "2147483647" on Windows 11. Mark speculated that the issue might be due to the Windows client using the INT data type instead of unsigned INT, leading to an overflow. He noted that over 50 policies are affected by this MaxValue issue across various components.

Gmail app bug locks some Microsoft 365 and Exchange Online users out on Android, Outlook still works

Android users are experiencing authentication issues with the Gmail app when trying to access Microsoft 365 or Exchange Online accounts, preventing access to work emails on mobile devices. This issue affects users across various devices, including Pixel, Samsung, Sony, OnePlus, Xiaomi, and Motorola, with reports from over 500 end users across 50 companies. The error message displayed is: “Check your account info or switch to modern authentication below. If you need help, contact your IT admin.” Attempts to delete and re-add accounts often worsen the situation. The problem may be linked to Microsoft enforcing Exchange ActiveSync (EAS) protocols, specifically a change implemented on March 1, 2026, requiring EAS version 16.1, which Gmail cannot meet. Outlook remains unaffected due to its use of a different sync protocol. Users have attempted various temporary solutions, such as clearing app cache and wiping app data, but these have proven unreliable. The most stable workaround currently recommended is to switch to the Outlook app for Android. Neither Google nor Microsoft has publicly addressed the authentication issues.

How Aurora Blue-Green Upgrades Cut Our Postgres Downtime by 50X

Paxos has implemented Blue-Green upgrades to improve database maintenance for asset trading, achieving a 50-fold reduction in downtime from 30-120 minutes to approximately one minute. This upgrade strategy allows for real-time synchronization between a blue cluster handling production traffic and a new green cluster with the updated version. Challenges included issues with CREATE ROLE statements disrupting upgrades due to temporary roles and the necessity to drop replication slots before PostgreSQL 17, which could lead to data loss. Additionally, upon the green cluster becoming primary, it acquires a new cluster ID, requiring updates for clients using RDS IAM authentication. The transition to PostgreSQL 17 is anticipated to resolve the need to drop logical replication slots, preserving Change Data Capture (CDC) continuity.

Microsoft enables Hotpatching by default: Windows updates without restarts become a reality

Beginning in May 2026, Microsoft will introduce Hotpatching as a default feature for compatible systems, allowing security updates to be applied without requiring a restart. Hotpatching updates code directly in the memory of running processes, enabling selective updates without interrupting the entire system. It does not replace monthly security updates but alters their activation process on eligible systems, categorized as security updates within the monthly B releases. Eligible systems must be running Windows 11 version 24H2 or newer and possess suitable licenses such as Enterprise, Education, Microsoft 365, or Windows 365. Management of these updates will be facilitated through Windows Autopatch or Microsoft Intune. Microsoft will continue to utilize baseline updates that require a restart, which will alternate with Hotpatch months. Hotpatching aims to reduce the frequency of restarts tied to security updates, particularly benefiting environments where uptime is critical. However, planned restarts will still be necessary, and robust telemetry and maintenance practices will be needed to ensure smooth operation.
