PostgreSQL Dump and Restore: The Complete pg_dump Guide

pg_dump is a utility for exporting a PostgreSQL database into a file, which can be restored on the same or different servers. It exports a single database's tables, views, sequences, functions, indexes, triggers, and in-database grants but does not include roles, tablespaces, or server-level configurations. To capture global objects, pg_dumpall --globals-only should be executed prior to the per-database dump. pg_dump requires CONNECT and SELECT privileges on all tables and sequences within the target database, and a dedicated backup role is sufficient for single-database dumps, while superuser access is needed for global objects. pg_dump supports various output formats: plain SQL (.sql), custom binary (.dump), directory of files, and tar archive (.tar), each with different capabilities for restoration and compression. The custom format allows for selective and parallel restoration. For non-interactive use, credentials can be stored in a .pgpass file or passed via the PGPASSWORD environment variable. Restoration methods depend on the dump format: psql is used for plain SQL files, while pg_restore is used for custom and directory formats. The restoration process requires the target database to be created beforehand. Version mismatches between pg_dump and pg_restore can lead to failures, so it's essential to ensure that the binaries are version-matched. In Docker, pg_dump and pg_restore can be executed within containers, but care must be taken to manage credentials and ensure version compatibility. Exit codes from pg_dump should be checked to confirm successful operations.

And Now I’ve Vibe Coded a Native Android Markdown App ⭐

The author developed a Markdown editor using Google AI Studio, initially intending to create a native Android application but ultimately producing a web app. They discovered a feature in Google AI Studio to build an Android app and crafted a prompt for a Markdown editor resembling Typora. The app includes file management, a WYSIWYG editing view, and keyboard shortcuts, with enhancements for hyperlink insertion and theme customization. The author successfully installed the app on a physical device and tested it on different configurations. They noted limitations in the testing capabilities of AI Studio and faced challenges transferring the project to Android Studio due to unclear instructions. The app is functional and feature-rich, but cannot be publicly shared due to the inclusion of a Google API key. Google has indicated that sharing on the Google Play Store will be possible in the future.

Google’s AI Studio now lets anyone build Android apps in minutes

The Google I/O 2026 event revealed enhanced native Android app creation capabilities within the web-based Google AI Studio, significantly reducing the app development time from weeks to minutes. Google introduced Gemini AI to help users discover applications on the Play Store and the web, improving user experience and developer visibility. The new platform allows users to "vibe-code" Android applications using intuitive tools, democratizing app development for both experienced and novice developers. Apps are developed using Kotlin and Google’s Jetpack Compose toolkit, with support for various hardware sensors. An embedded Android Emulator enables real-time preview and interaction with apps, which can be installed on devices via USB. AI Studio also offers features for creating app records, package bundles, and uploading to the Google Play Console for internal testing. Developers can transfer projects to Android Studio for broader publishing, with future enhancements including app sharing and Firebase integrations. A new AI-powered overlay called "Ask Play" will assist users in discovering apps through natural conversations, while Gemini will help surface developers' apps and link users to movies, TV shows, and live sports streaming.

Why I’m still tweaking Windows 11’s Registry, even after April’s “improvements”

Windows 11's April update includes performance boosts, a refined File Explorer, and a revamped Settings app, but primarily addresses existing issues rather than customization preferences. Users still face challenges with the lack of easily accessible customization options, leading many to rely on registry tweaks to adjust settings not available through the standard Settings menu. Key registry modifications include restoring the classic right-click menu, adding an "End Task" option to the taskbar's right-click menu, disabling Bing search in the Start menu, and removing the Recommended section from the Start Menu. These tweaks enhance functionality and convenience, as the updates do not sufficiently address user customizability concerns.
