Unlock Hidden PostgreSQL Speed: 3 Unconventional Optimization Techniques You’re Missing

Unlock PostgreSQL Performance: 3 Unconventional Optimization Techniques When it comes to database optimization, most developers rely on the same familiar toolkit—tweaking queries, adding indexes to columns, denormalizing data, and repeating cycles of analyzing, vacuuming, and clustering. Conventional methods work, but thinking outside the box can deliver transformative performance gains for PostgreSQL. In this article, we’ll break down three practical yet underutilized PostgreSQL optimization strategies: eliminating pointless full table scans, optimizing indexes for low-cardinality scenarios, and enforcing uniqueness with hash indexes. Each addresses real-world performance pain points with actionable solutions. I. Eliminate Meaningless Full Table Scans with Check Constraints In daily …
