Background & analysis
On November 12, 2026, a Juejin article titled "Postgres Slow Query Tuning Guide: Beware of Index Pitfalls in AI-Generated SQL" appeared, reflecting a discussion among developers about the performance risks introduced when SQL is written with AI assistance.
The piece points out that such SQL often runs quickly during testing, yet an interface may suddenly slow down or time out one day without an obvious cause. To investigate Postgres slow queries, the article describes concrete steps for gathering evidence and tuning queries with pg_stat_statements. It also argues that "just add an index" can be risky on Postgres, and that blindly adding indexes may create problems rather than fix them.
The article stands as the only published report so far, and no further documented developments have emerged.
