Rollback

Schemage stores executed operations and rollback SQL in its migration history infrastructure.

Roll back the latest batch:

vendor/bin/schemage --rollback

Preview rollback SQL:

vendor/bin/schemage --rollback --dry-run

Rollback availability depends on whether the original operation has enough metadata for a safe inverse.

Operation	Typical inverse
Add column	Drop column
Modify column	Restore the previous definition
Rename column	Rename it back
Rename table	Rename it back
Add index	Drop index
Drop index	Recreate the previous index when metadata was recorded
Add foreign key	Drop foreign key
Drop foreign key	Recreate the previous foreign key when metadata was recorded

Dropping a table or column cannot automatically restore deleted row data.
