Query Plan Hints in PostgreSQL 19: A New Postgres Feature You Will Probably Never Need

PostgreSQL 19 features an advanced query planner that utilizes table statistics from pg_statistic, gathered during the ANALYZE process, to generate and evaluate potential query plans based on their costs. The planner assesses various configurations, especially in complex joins, to select the most efficient option. Instances of poor planning are treated as bugs and addressed promptly. To improve query performance, users are advised to refresh statistics with ANALYZE, use CREATE STATISTICS for column correlations, modify indexes, and adjust memory settings. In cases where the query cannot be altered, providing planner advice may be necessary, particularly when the planner misestimates the output of PL/pgSQL functions or other custom functions, leading to inefficient query execution.

AWS embeds DuckDB in its PostgreSQL DBMS to speed queries of live and historical data

Amazon Web Services Inc. has enhanced its Aurora PostgreSQL database management system to allow users to query the Apache Iceberg data lake directly. This feature integrates the DuckDB analytical engine, enabling seamless access to live transactions and historical records without data duplication or complex ETL processes. Customers can use existing PostgreSQL applications to query data in Amazon S3, including S3 Tables. The integration aims to reduce the engineering workload associated with data pipelines and supports real-time applications. DuckDB processes analytical scans within Aurora, eliminating extra network hops and allowing single queries to access both live and archived data. The feature supports external catalogs compliant with the Iceberg REST Catalog specification and can create foreign tables referencing data across multiple catalogs. Aurora optimizes query performance by filtering records and caching frequently accessed data. Customers can combine recent transactions in Aurora with historical data from S3 without manual schema definitions. For low-latency workloads, selected data can be copied into native Aurora tables using standard SQL. This capability requires the aurora_analytics extension and an AWS IAM role for S3 and Glue access, and is compatible with Aurora PostgreSQL versions 17.11 and 18.6. The feature is available across all AWS regions at no additional charge, with costs incurred only for Aurora computing resources and S3 requests.

Designing a Concurrent Donation Ledger With FastAPI and PostgreSQL

Every year, billions of dollars flow through online crowdfunding platforms, leading to donor concerns about the allocation of funds. Traditional crowdfunding applications lack transparency, often leaving funds in unverified balances without real-time auditability or guarantees against double-allocations. GoodCause, a social impact platform, aims to address this issue by creating a system that ensures financial integrity and atomic fund distribution. Its architecture is based on mobile-first delivery, atomic auditability, and strict data isolation, utilizing technologies such as React Native, FastAPI, and PostgreSQL. The platform incorporates a mobile client for cross-platform navigation, a backend API for domain-driven routing, a database with Row-Level Security, and a payment gateway for secure transactions. A significant engineering challenge is preventing race conditions and double-spending in concurrent donation scenarios.

Why Antivirus Flags Game Tools and How to Verify Downloads Safely

In gaming, tools such as utilities, beta applications, and modding tools are often distributed as APK, IPA, or desktop files, and it is essential to investigate their origin, version, and any security warnings before installation. Antivirus software flags potential threats based on known malicious signatures, behavior patterns, and reputation data. Tools that modify game clients may receive heightened scrutiny, and classifications like “HackTool” or “Riskware” do not definitively indicate a file's functionality. Identical game utilities can exist on various platforms, and a familiar website does not guarantee authenticity. It is crucial to verify the publisher, update date, version, and installation method of a file. The SHA-256 hash verifies file integrity but does not ensure safety from malware. Calculating a file hash can be done using specific commands in Windows, macOS, or Linux. Multi-engine scanning platforms like VirusTotal provide insights, but a lack of detections does not guarantee safety. Even if a file matches its reference hash and raises no alerts, it may still violate online game terms. A pre-installation checklist includes confirming the publisher, checking file types, comparing SHA-256 hashes, reviewing security findings, keeping antivirus protection enabled, and consulting platform rules. A cautious approach integrates source verification, file integrity checks, security assessments, and compliance with platform regulations.

How and why we built Managed PostgreSQL for AI workloads

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.
