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.

PostgreSQL vs SQL Server 2026: $0 vs $15K License

PostgreSQL has become the most utilized database for developers for two consecutive years as of 2026, while SQL Server has introduced native AI capabilities and vector search functionalities in its latest release. PostgreSQL is favored for new projects due to its permissive licensing, cross-platform operation, and extensive ecosystem of extensions, whereas SQL Server is preferred by organizations already using Microsoft products for its robust tooling and enterprise support. As of June 2026, SQL Server ranks third in the DB-Engines popularity ranking with a score of 698, while PostgreSQL ranks fourth with a score of 688. Developer adoption trends show that 49% of respondents in the Stack Overflow 2024 Developer Survey use PostgreSQL, compared to 27% for SQL Server. The latest stable version of PostgreSQL is 18.4, released on May 14, 2026, while SQL Server 2025 (version 17.x) became generally available on November 18, 2025. PostgreSQL is free under a permissive license, while SQL Server's Enterprise Edition can cost upwards of ,123 per two-core pack, with an eight-core minimum. PostgreSQL supports various operating systems, including Linux, Windows, macOS, and BSD, while SQL Server operates on Windows and Linux. PostgreSQL uses PL/pgSQL as its primary procedural language, allowing for multiple procedural languages, whereas SQL Server uses T-SQL. PostgreSQL's JSONB type offers rich indexing, while SQL Server added native JSON support in its 2025 release. Both databases are capable of handling high transaction volumes, but PostgreSQL excels in read-heavy scenarios due to its multi-version concurrency control, while SQL Server's columnstore indexes provide advantages for analytical workloads. PostgreSQL supports tables up to 32 TB, while SQL Server can handle a maximum database size of 524 PB. SQL Server's high availability technology includes Always On Availability Groups, while PostgreSQL offers built-in streaming and logical replication. The security features of both databases meet enterprise standards, with PostgreSQL providing a transparent patching process and SQL Server integrating with Microsoft tools. Real-world usage examples include Stack Overflow using SQL Server, while Instagram and Reddit utilize PostgreSQL. Developer sentiment increasingly favors PostgreSQL for new projects, emphasizing flexibility and open-source solutions. For new startups or greenfield projects, PostgreSQL is recommended due to its zero license cost and compatibility. Existing Microsoft enterprises are advised to stick with SQL Server for its integration benefits. Migration from SQL Server to PostgreSQL is becoming common, with a structured approach required for successful transitions.

Apple removes Russia’s state-backed messaging app Max from its store

Apple has removed the state-backed messaging app Max from its App Store, leading to criticism from Russian officials who deemed the action "unfriendly." Max is no longer available for download on iPhones and iPads, although existing users can still access it without updates. Russia's Digital Development Minister, Maksut Shadaev, stated that the removal denies access to about 20 million Russians and that Apple provided no explanation to the app's developers. Apple cited compliance with sanctions regulations as the reason for the removal but did not specify which sanctions. Max remains available on Android devices through Google Play and RuStore. The app, promoted by Russian authorities as an alternative to foreign platforms, was developed by VK and integrates messaging, voice calls, and access to government services. At the time of removal, Max was the ninth most downloaded app in Russia's App Store. Russian officials have criticized Apple, with some labeling the company as "enemies." Digital rights advocates have raised concerns about Max's ties to the government and lack of encryption, suggesting potential monitoring of users. Apple has a history of removing apps from the Russian store, but Max's removal does not appear to be linked to a specific government request.

Microsoft Promises Customizable Windows Right-Click Menus

Microsoft is working on a more efficient, streamlined, and customizable right-click context menu for Windows File Explorer and Desktop interactions, responding to user feedback about the cluttered nature of existing menus. The initiative aims to improve user experience by allowing customization, which marks a shift from Microsoft's previous rigid approach. Developers will need to adapt to new APIs and guidelines for context menu interactions, and there may be restrictions on the number of items that can be added. Performance improvements are also planned to address slow-loading context menus. The timeline for implementation is uncertain, but updates may first appear through Windows Insider testing channels. The changes are part of Microsoft's broader strategy to modernize Windows 11 and improve basic functionalities like file management and interface responsiveness. Customizable context menus could provide enterprise IT departments with new management options, and the initiative reflects Microsoft's awareness of competition from other operating systems.

A guide to agentic AI: How Windows is now going to do more things for you

Microsoft is advancing in the field of artificial intelligence with the introduction of agentic AI, which aims to perform tasks on behalf of users rather than just responding to queries. A key feature is 'autoagents,' starting with Scout, which will integrate into Microsoft 365 applications and autonomously manage tasks like monitoring communications and summarizing documents. Scout is currently being rolled out to select users and is designed with safety measures, including Execution Containers to control resource access and mitigate risks. Additionally, Microsoft has launched Discovery, a tool for enhancing scientific research, and Rayfin, which simplifies application development for individual creators.
