PostgreSQL 18 on Amazon Aurora and Amazon RDS: Performance enhancements

PostgreSQL 18 addresses common performance challenges for users, including managing query performance across composite indexes, diagnosing memory spills in materialized Common Table Expressions (CTEs), and upgrading major versions without plan regressions. Key enhancements include skip scan optimization for multicolumn indexes, improved EXPLAIN functionality, and optimizer statistics that persist through major version upgrades. Skip scan optimization allows PostgreSQL to efficiently utilize multicolumn B-tree indexes even when leading columns are not specified in the WHERE clause, significantly improving query performance. The EXPLAIN command has been enhanced to include buffer statistics by default, providing deeper insights into query execution and resource usage. PostgreSQL 18 also introduces visibility into the storage of materialized nodes in query plans, indicating whether intermediate results were stored in memory or spilled to disk. A new metric, Index Searches, has been added to EXPLAIN ANALYZE output, indicating how many times the database traversed the index tree during query execution. Additionally, Self-Join Elimination (SJE) automatically detects and removes unnecessary inner joins of a table to itself, optimizing query performance. The autovacuum mechanism has been improved with the introduction of autovacuum_vacuum_max_threshold, which caps the number of dead tuples that can accumulate before autovacuum triggers a VACUUM, addressing issues with large tables. The vacuum_truncate parameter provides a server-wide control point to disable VACUUM’s file truncation behavior, reducing locking issues on busy systems. PostgreSQL 18 also separates the allocation of autovacuum worker slots from their usage, allowing for dynamic adjustments to autovacuum_max_workers without requiring a server restart. Finally, new columns in pg_stat_all_tables track cumulative time spent on maintenance operations, providing better insights into maintenance overhead for each table.

Microsoft finally admits its default Windows 11 25H2, 24H2 action broke key legacy component

Microsoft released Patch Tuesday updates for Windows 11, specifically KB5094126 and KB5093998, along with dynamic updates KB5094149, KB5095971, and KB5094156. Two issues have been acknowledged: malfunctioning Office applications and complications with the Recycle Bin. In July 2025, Microsoft changed the default settings of Windows 11 to JScript9Legacy in versions 24H2 and later, continuing with version 25H2 in October 2025. This change aimed to enhance security by addressing vulnerabilities related to legacy scripting, particularly cross-site scripting (XSS). A support article details a compatibility issue arising from the transition from jscript9.dll to jscript9legacy.dll, which affects how JScript manages execution context. Functions and definitions established by one script are no longer accessible to subsequent scripts, leading to failures in legacy applications. To address this, Microsoft released the KB5077241 update, which requires manual activation of persistent JScript execution context through a Registry setting. The steps to implement this solution involve creating a feature control registry key and configuring a DWORD value for specific processes or all processes.

Microsoft Teams will auto-detect when you’re at the office via Wi-Fi, roll out confirmed, but you can opt-out

Microsoft is rolling out a feature called "Workplace check-in" that allows organizations to track employee presence in the office through Wi-Fi connectivity, integrated with Microsoft Teams and configured via Microsoft Places. This feature, first noted in September 2025, will not be enabled by default. It logs an employee's location when they connect to the company’s Wi-Fi, such as when they arrive at the office. The rollout was delayed due to privacy concerns, but Microsoft is moving forward, ensuring users can control their participation. The feature does not provide real-time tracking like mapping services but indicates presence based on Wi-Fi connection. Users must grant location access through their operating system, and if they decline, IT policies cannot override this choice. Teams’ Workplace check-in is disabled by default and can be activated by IT administrators with two options: Inform mode, which notifies users of the feature and allows opting out, and Ask mode, which requests permission to share location data. Microsoft clarifies that the feature is not intended for surveillance and does not track movements over time. Employees can choose whether their presence is visible to others while on-site. The initial rollout is tied to organizations using the Microsoft Places directory, and as organizations set up the feature, more users will likely be affected. Additionally, Microsoft is enhancing Teams with improvements for speed and a new user interface for meetings.

Automate Amazon Aurora PostgreSQL major or minor version upgrade using AWS Systems Manager and Amazon EC2

Managing upgrades for the Aurora PostgreSQL-Compatible Edition can be labor-intensive and error-prone when done manually. Automating Amazon Aurora PostgreSQL upgrades can reduce manual effort by up to 80% and minimize downtime risks through consistent procedures. The automation solution uses AWS Systems Manager, Amazon EC2, and AWS Secrets Manager, structured around two modules: PREUPGRADE for readiness checks and UPGRADE for the actual upgrade process. The solution identifies upgrade candidates using database tags, creates safety backups with Copy-on-Write clones, manages the upgrade process with minimal human intervention, and offers real-time monitoring and email notifications. The workflow includes logging into the Systems Manager console, downloading the upgrade script, identifying Aurora PostgreSQL clusters based on tags, retrieving credentials from AWS Secrets Manager, executing pre-upgrade checks or upgrades, uploading log files to Amazon S3, and sending email notifications via Amazon SNS. Prerequisites include familiarity with the Aurora upgrade process, appropriate IAM permissions, creating a maintenance user, setting up AWS Secrets Manager, tagging Aurora clusters, creating an S3 bucket, and configuring an SNS topic for notifications. Implementation steps involve reviewing setup instructions, uploading the upgrade script to S3, creating an AWS Systems Manager automation document, executing the automation document, and monitoring the upgrade process through logs generated during pre-upgrade and upgrade phases. The logs provide detailed information on tasks performed, including replication slot status and configuration backups. After testing, it is recommended to clean up resources to avoid future charges.

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.

Implementing real-time change data capture with Debezium for Amazon Aurora PostgreSQL and Amazon RDS for PostgreSQL

Amazon Aurora PostgreSQL-Compatible Edition and Amazon RDS for PostgreSQL support native streaming replication, allowing data changes to flow from source databases. Organizations often struggle with real-time data capture and dissemination, leading to outdated information due to traditional batch ETL pipelines. Debezium is an open-source platform for change data capture (CDC) that streams database changes to applications or data pipelines in real time. The CDC solution utilizes PostgreSQL's logical replication capabilities and Debezium's framework. Key components include Amazon Aurora for PostgreSQL as the source database, a Debezium PostgreSQL connector on MSK Connect, Amazon MSK for message streaming, and an Amazon EC2 instance for testing. To implement the solution, users must enable logical replication on Amazon Aurora, create an Amazon MSK cluster, set up an EC2 instance with Kafka, and create a custom plugin for MSK Connect. The process involves configuring IAM roles and policies, connecting to the database, and creating an Amazon MSK connector to stream changes. Testing the solution includes verifying real-time changes by inserting, updating, and deleting records in PostgreSQL, with events appearing in Kafka. Monitoring tools are available through CloudWatch for troubleshooting issues like replication slot lag and connector failures. To clean up resources after testing, users should delete the MSK Connect connector, custom plugin, Amazon MSK cluster, Aurora PostgreSQL database instance, EC2 instance, IAM role and policy, Secrets Manager secrets, CloudWatch Logs log group, and S3 bucket.
