How a PostgreSQL CHECK constraint silently broke an entire CRM
A CHECK constraint on a region column in a PostgreSQL table caused parent transactions to abort when new region values were inserted via a trigger. The error propagated silently, rolling back the entire contact creation process without useful feedback. The lesson: constraints encode assumptions that column names don't, and triggers can hide failures.

This is a cautionary tale about database schema design and the hidden dangers of trigger-based logic, but the core issue—poor documentation and lack of defensive coding—is a basic engineering discipline failure.
