db-migrations
Use when a schema change must ship without downtime — NOT NULL, rename, type change, or backfilling millions of live rows — for the expand-contract sequence and the lock/batching discipline that keeps each step from freezing prod. NOT lock internals or EXPLAIN (that is postgresdb), NOT drizzle-kit mechanics (that is drizzle-orm), NOT PITR (that is backups).
