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.

Трёхмерная реконструкция аварий на трассе А-7: Патерна, Пикассент и Торрент

The operation "Exit" in Valencia province led to three simultaneous accidents on the A-7 highway, causing over six kilometers of traffic congestion. Accident analysts utilize three-dimensional documentation, including digital photogrammetry and laser scanning (LiDAR), to accurately capture collision points and vehicle trajectories. This data helps determine liability and structural deficiencies. The 3D models created allow for the calculation of impact speeds and simulation of vehicle interactions. Additionally, these technologies enable predictive simulations to test modifications for traffic management and improve safety measures, ultimately aiming to reduce accident rates on busy corridors.

Backstage Ditches Postgres for Databricks Lakebase

The divide between operational and analytical databases is diminishing, as evidenced by Databricks integrating Spotify's Backstage with its Lakebase, transitioning from PostgreSQL to a unified data platform. Lakebase now offers a serverless PostgreSQL interface within Databricks, allowing Backstage to operate without awareness of the underlying changes. The integration involved updating configurations and addressing authentication challenges using OAuth JWTs. The integration transforms the database development lifecycle by enabling near-instant database branching through Lakebase's copy-on-write architecture, allowing developers to focus on testing changes rather than safety. Branching creates a pointer to existing data, making the operation instantaneous. Point-in-Time Recovery (PITR) allows for quick restoration of data, demonstrated by a recovery process that took less than four seconds. The goal is to integrate database branching into developer workflows seamlessly, making it automatic. This change could enhance developer productivity by allowing live data testing from the start, eliminating the need for mock objects, and resolving common issues related to staging environments. The traditional constraints of slow and costly database copies will become obsolete, prompting teams to reconsider how much time they spend on workarounds for now-nonexistent constraints.

These games made us all upgrade our PCs

PC enthusiasts often delay hardware upgrades until necessary, but certain games can compel upgrades due to their advanced technology and demanding graphics. Half-Life 2, released in 2004, introduced real-time physics and advanced graphics, leading to a surge in demand for GeForce 6600 and Radeon X800 graphics cards as players sought smoother performance. Grand Theft Auto IV, released in 2008, required robust quad-core processors for optimal performance due to its CPU-intensive simulations, prompting players to upgrade their CPUs. Crysis, launched in 2007, set a new standard for graphical fidelity with its advanced features, becoming a benchmark for PC performance and prompting gamers to upgrade their systems. The Witcher 3: Wild Hunt, released in 2015, utilized cutting-edge technologies that made midrange builds struggle, leading players to upgrade for better performance and visuals. Cyberpunk 2077, released in 2020, created a surge in demand for NVIDIA's RTX 20-series GPUs as players sought to experience its high graphical fidelity, prompting many gamers to upgrade their systems.

PostgreSQL Gains a Built-in UUIDv7 Generation Function for Primary Keys

In late September 2025, PostgreSQL 18 introduced the built-in function uuidv7(), which generates UUID version 7 identifiers according to RFC 9562. UUIDv7 offers global uniqueness, low collision probability, and allows ordering by generation timestamp, improving performance and reducing index sizes compared to UUIDv4. It addresses limitations of auto-increment identifiers, such as challenges in data merging and key collision errors. The uuidv7() function features a 12-bit sub-millisecond timestamp segment, operates without a mutex, and requires a cryptographically secure pseudo-random number generator. It ensures monotonicity and uniqueness even under critical conditions, and can offset timestamps to mask record creation dates. Example usage includes creating a clients table with UUIDv7 as the primary key and inserting records with generated UUIDs.
