How to Improve PostgreSQL Query Performance: 2026 Guide

2026-08-15 · postgresql, query optimization, database performance, indexing, EXPLAIN ANALYZE

PostgreSQL's query planner is powerful but not magic — poor cardinality estimates and missing indexes regularly cause 10x–100x performance gaps. A 2026 VLDB paper on batch query evaluation achieved 2x–178x speedups by rethinking how counting queries are structured, and the same principles apply to everyday application queries.

PostgreSQL Performance Tuning: Key Parameters That Matter

2026-08-05 · PostgreSQL, database performance, shared_buffers, NVMe, query optimization

A 2024 arXiv study on PostgreSQL running on NVMe storage shows how dramatically the storage subsystem shapes query throughput — but only when the database is configured to exploit it. This guide covers the postgresql.conf parameters that separate a default install from a production-ready database.
