Microsoft has released an emergency update for Windows 10 due to issues following May’s mandatory security update, which caused BitLocker Recovery screens and Blue Screens of Death for users. The problem primarily affects devices with Intel Trusted Execution Technology on 10th generation or later Intel vPro processors. Users who encounter these issues are advised to disable Intel VT for Direct I/O and Intel TXT in BIOS/UEFI settings, install update KB5061768, and then re-enable the settings. Microsoft has stated that its support team cannot retrieve lost BitLocker recovery keys. This issue mainly impacts enterprise users, as consumer devices generally do not use Intel vPro processors.

Microsoft has announced that Windows 11 version 24H2 has officially entered the final phase of its gradual rollout, making it available to all users. This automatic installation applies to individual users of Home and Pro editions of Windows 11 versions 23H2, 22H2, and 21H2, excluding managed organizations or enterprises. Devices blocked due to known bugs are exempt from the update. Users can choose when to restart their devices or postpone the update, and they can also pause updates for one to five weeks. Users can manually check for the update by navigating to Settings and selecting Windows Update. Since its release, Windows 11 24H2 has faced various bugs and compatibility issues, leading to some updates being blocked and creating a cycle of fixes and new problems. As Windows 10 approaches its end of support in October, the need for stability in Windows 11 is becoming increasingly important.

pgpro_tune is a command-line utility designed to optimize the initial server configuration of Postgres Pro based on hardware specifications. It scans the server to identify key hardware details, processes these values through shell scripts that encapsulate tuning expertise, and generates recommended parameters for PostgreSQL settings, including memory management, autovacuum tuning, connection limits, and statistics collection. The utility appends these settings to the postgresql.conf file, ensuring they override the default settings. pgpro_tune supports various presets for different use cases and allows database administrators to create custom presets. It runs automatically during cluster initialization and can be executed manually at any time, applying changes through standard PostgreSQL methods. This tool aims to streamline the tuning process, reduce the risks of misconfiguration, and enhance performance without replacing the need for advanced tuning in specialized scenarios.

PostgreSQL 18 includes significant enhancements in monitoring capabilities and new features. Key updates include: - Buffer information in EXPLAIN ANALYZE is now enabled by default, providing detailed buffer statistics for better query performance insights. - The pg_stat_io view tracks I/O statistics in bytes (read_bytes, write_bytes, extend_bytes), simplifying monitoring of I/O operations. - Enhanced monitoring of Write-Ahead Logging (WAL) statistics is introduced, allowing tracking of WAL operations and new WAL segment initialization. - The pg_stat_get_backend_io function provides I/O statistics for specific client processes, aiding in performance tuning. - The VACUUM (verbose) command now includes visibility map information, detailing all-visible pages after a vacuum operation. - The pg_stat_all_table view tracks total vacuum and analysis times per table, and users can adjust autovacuum workers without server restarts. - A new uuidv7 function generates UUIDs with a Unix-epoch timestamp for ordered identifiers. - The passwordcheck extension enforces a minimum password length for better security practices. - Improvements to the jsonb type ensure correct handling of null conversions. - The casefold function facilitates case-insensitive searches. - The RETURNING clause in DML commands now supports returning both old and new values. - The to_number function can convert Roman numerals to numeric values.

The AWS Database Migration Service (AWS DMS) provides a managed solution for migrating and replicating databases to AWS, supporting both homogeneous and heterogeneous migrations. It allows seamless data migration from PostgreSQL databases to any supported target and vice versa. Open-source PostgreSQL regularly releases new versions, and Amazon RDS aims to support these within five months. Upgrading PostgreSQL instances is essential for security and compliance. Minor version upgrades focus on security and bug fixes without adding new functionalities, while major upgrades can change system tables and data formats. AWS DMS tasks require careful management during PostgreSQL upgrades. For minor upgrades, ongoing DMS tasks should be stopped and then resumed post-upgrade. For major upgrades, replication slots must be dropped before the upgrade, which will invalidate ongoing DMS tasks. After the upgrade, a new CDC-only task should be created to resume data migration. Minor version upgrades of the target PostgreSQL database do not affect AWS DMS CDC tasks, but major upgrades require stopping the DMS task, performing the upgrade, and ensuring compatibility with the replication instance before resuming the task.
