10 Years of Postgres Expertise: 'Claude Just Made the Whole Team a Postgres Expert'
RealGeneKim · x · 2026-11-14
A viral Reddit post from a database engineer with 10 years of Postgres expertise describes a junior teammate who asked Claude to fix a slow query — it read the execution plan, suggested a partial index and rewrite, and was right, even though the junior didn't understand why.
The author reflects that a decade of deep expertise is now something anyone can approximate in 2 minutes. He isn't bitter and uses the tool all day, but wonders what his "thing" is anymore: knowing when the model is wrong still matters, yet is hard to point at in a performance review.
