PostgreSQL's core team hit a hard constraint: their AI-assisted review process found more bugs than the volunteer developer base could realistically fix before release, forcing a multi-month delay and reverting ten features. Automation surfaces problems faster than organizational capacity can resolve them, creating a new bottleneck in open-source development where detection outpaces remediation. The calculus has shifted from "ship it when reviewers say yes" to "ship it when the defect queue matches our actual repair velocity."
