Adding a New Column Without Breaking Your Database

A new column in a database is simple in theory. One ALTER TABLE and it exists. But getting it right means aligning migrations, ensuring backward compatibility, preventing downtime, and keeping data consistent. Push it too fast and you break systems; push it too slow and you stall progress. Start with
