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.

Google exec shares an AI Mode change for sources that makes it even easier to fact-check

Google has introduced an update to its Search platform that enhances AI Mode and AI Overviews. The update includes "groups of links" accessible through a floating sub-menu when users hover over the link icon, which has been redesigned for better visibility. This feature is currently available only for desktop users, while mobile users will continue to tap links as usual. AI Mode can assist with appointment bookings by requiring users to fill out a brief form, after which it summarizes the information gathered. Earlier this year, Google integrated its AI model, Gemini 3, into AI Overviews, allowing users to ask follow-up questions more quickly while retaining context.

As Windows turns 40, Microsoft faces an AI backlash

Microsoft is transforming Windows into an "agentic OS" by integrating advanced AI capabilities, as announced at the Ignite conference. The reception has been mixed, with users expressing concerns similar to those after the release of Windows 8. Windows chief Pavan Davuluri faced criticism on social media regarding the initiative, with users calling for a return to simpler interfaces like Windows 7. Despite acknowledging user pain points, many feel that the focus on AI features overshadows necessary improvements. The integration of AI tools like Copilot has received mixed reviews, with reports of unreliability. CEO Satya Nadella envisions a shift towards AI agents performing tasks, while also emphasizing the need for user control over their experience. Microsoft aims to balance innovation with user preferences, allowing users to opt-in to AI features at their own pace. Recent developments include a hotfix driver from Nvidia for Windows 11 performance issues, the return of a calendar feature to Windows 11, integration of Google's AI models into GitHub Copilot, and enhancements in security and performance for Windows and Office applications.
