// --- Migration Guide line ---
// 1. Never change a migration that is committed and pushed to main
// 2. Always add new migrations (to change or undo previous migrations)
// 3. Some migrations are not yet written (rename column, table, drop table, index etc)
// 4. Putting migrations behind feature flags is no longer recommended as broken
//    migrations may not be caught by integration tests unless feature flags are
//    specifically added
