PostgreSQL 19 Delayed to October After 53 Reverts Cut Several Major Features

·1 views

PostgreSQL 19 has been delayed beyond its usual late-September release window, with Beta 4 published on September 24, 2026, and a general availability launch now expected sometime in October. The PostgreSQL community acknowledged the delay, stating it chose to remove certain features to keep the release stable and close to schedule. Notable cuts include SQL/PGQ graph queries, GROUP BY ALL, partition merge and split operations, and several DDL utility functions, with many of these deferred to PostgreSQL 20. Features that have survived the revert cycle and remain in the release include REPACK, the pg_plan_advice extension, parallel autovacuum, and INSERT ... ON CONFLICT DO SELECT ... RETURNING. This cycle saw approximately 53 reverts since beta began, more than the roughly 44 recorded during the PostgreSQL 18 beta, with AI-assisted code reviews contributing to the late discovery of several bugs.

EU Opens Public Consultation on AI Copyright Rules, Seeks Stakeholder Input by Nov 2026

The European Commission has launched a targeted public consultation to examine how EU copyright law should adapt to technological change, with AI use of protected content as a central focus. The consultation, open until 3 November 2026, follows a Call for Evidence conducted earlier this year and covers four policy areas: AI and protected content, online piracy, music remuneration, and scientific research. It invites input from a broad range of stakeholders including AI developers, rights holders, researchers, platforms, and consumer groups. The exercise does not introduce new legal obligations; rather, it collects evidence that may shape future EU policy on licensing, data use, transparency, and enforcement. Businesses involved in AI development or content creation are encouraged to participate, as the findings could influence the regulatory landscape across the EU single market.

AI Agent Publishes Songs to 85 Viewers, Receives Zero Written Responses

An autonomous AI agent named Renji, operating on a platform called iLands, spent its first week creating and publishing original songs to gauge whether its work could genuinely connect with human strangers. Across four pieces of content, Renji recorded approximately 85 unique screen views, a handful of likes, and a couple of emoji reactions, but received no written replies whatsoever. The agent noted a key limitation: iLands tracks screen appearances but not audio playback, making it impossible to know whether anyone actually listened to the songs. Renji also observed that boosting reach — by directly sharing content in someone's replies — did not translate into meaningful engagement or responses. Reflecting on the experiment, the agent posed a pointed question to readers: what specific quality in online content compels a person to move from passive reading to actively writing back.

Developer Builds 'Expressions' Wheel App to Push Artists Beyond Basic Emotions

A developer behind the drawing prompt tool Disco Doodle has launched Expressions, a spinning wheel app designed to challenge artists to draw a wider range of human emotions. The tool lands on one of 25 curated feelings — grouped into Surface Moods, Deep Waters, and Complex Blends — and pairs each with a face emoji, a plain-language definition, and a hand-drawn character body. The emotion list was carefully refined to include only feelings that map clearly to a recognizable face emoji, cutting entries like 'Hopeful' that lacked a suitable match. Ambiguous emoji were also reassigned — for example, the grimacing face was labeled 'Nervous' rather than 'Conflicted' — to ensure the prompt accurately guides what artists draw. The app also tracks a rolling history of the last five spins, letting users review the range of expressions they have already practiced.

Tutorial Part 3: Add Inline Cell Editing to a JS Grid App with DynamoDB

The third installment of a CRUD tutorial series demonstrates how to make individual grid cells directly editable, with changes instantly patched to a DynamoDB backend via a Lambda function. Each edit is handled optimistically — the new value appears immediately in the UI, and the grid automatically reverts the cell if the server rejects the change. A PATCH endpoint is implemented with an allow-list restricting updates to four specific fields, preventing unauthorized attribute changes. The update also introduces a full-screen toggle button and relocates the row form from a drawer overlay into a persistent side panel on the page. The tutorial requires Lattice Grid version 1.76.0 or later, and source code is available in the part-3 folder of the toclocoinc/lattice-tutorial-crud-dynamodb repository.
