What was the turning point for Postgres? PlanetScale traces the database's path to AI-era default
rseroter · x · 2026-10-29
PlanetScale's Simeon Griggs traces how Postgres, a database from the 1980s, became the default choice for developers and AI agents.
- The evidence: tools tracking LLM database preferences show Postgres dominating across 32,955 LLM decisions; whether builders choose it knowingly or agents pick it for them, it's the default for new apps.
- Working backward: the post walks back from 2025 (when investors and cloud providers poured money into the Postgres ecosystem) through earlier pivotal moments, trying to pinpoint the most consequential one.
- Addressing objections: MySQL isn't dead (WordPress' massive install base persists) and Oracle still edges out on revenue, but the trend data is clear.
- Core question: did Postgres win via decades-old foundations, resilience against competitors, or simply timing the agentic era right?
