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.

How Five PostgreSQL Optimizations Sped Up Our Dashboard

The dashboard operates on a Django monolith with PostgreSQL and is transitioning to ClickHouse for denormalization. The initial p50 metric was 0.7 seconds, but the p95 was 8 seconds, which was reduced to 1 second. Observability tools were established to monitor performance, and slow HTTP requests were identified using OpenTelemetry traces. Optimization techniques included late joining, asynchronous counting, creating a PostgreSQL replica for read operations, and improving full-text search. Denormalization was explored to enhance filtering performance by creating composite indexes. The production stack was upgraded to PostgreSQL 18, which provided incremental performance improvements. The final p95 value achieved was 1 second, below the target of 3 seconds.

Fake ChatGPT download site infects Windows and Mac users with malware

A counterfeit website, openew[.]app, is impersonating OpenAI's official ChatGPT download page and distributing malware. Windows users who download from this site receive a credential-stealing malware loader, while macOS users are infected with Odyssey Stealer, a variant associated with cryptocurrency theft. The fake site mimics the legitimate ChatGPT interface and uses HTTPS to appear trustworthy. The Windows malware, Chat_GPT.exe, creates a back channel to an attacker-controlled server, while the macOS malware captures sensitive data and attempts to replace legitimate cryptocurrency wallet applications with compromised versions. Users who download from official sources remain safe, but those who click on ads or unfamiliar links risk compromising their online accounts and sensitive information. Malwarebytes offers protection against this malware. Indicators of compromise include specific file hashes and network indicators associated with the malicious site.
