Good morning, it's June 12th, 2026. I'm your host with today's PostgreSQL development briefing.
The PostgreSQL team pushed through a series of critical security and stability fixes yesterday, addressing vulnerabilities that could allow constraint bypasses and system crashes.
The most severe issues centered around foreign key constraint enforcement. Commits 4113873 and 0e47bb5 by Amit Langote fixed multiple bugs in the fast-path batching system that could allow orphaned rows to bypass foreign key checks entirely. The first fix addresses how the system handles subtransactions -…
Authentication security also received attention. Commit 44196fd fixed MD5 password warnings that weren't respecting role-level settings, allowing administrators to properly control warning behavior at the user and database level. Meanwhile, commit a8ee70b addressed a race condition during server promotion that could…
