How to Safely Add a New Column to Your Database

Adding a new column sounds simple, but it can fracture production if done without care. The schema, indexes, and application logic must align. Downtime, locks, and failed migrations all lurk if the change is rushed. Every database—PostgreSQL, MySQL, SQLite—handles new columns differently. Some write instantly to metadata. Others
