The data model changes. You need a new column.

Adding a new column can feel trivial, but in production systems it is never just one line of SQL. Schema changes carry risk. They expose performance bottlenecks, migration downtime, and backward compatibility issues. Done wrong, even a single column can break your API, corrupt data, or force an emergency rollback.
