Your Question
I am having the same Issue as in https://github.com/go-gorm/gorm/issues/3973. I undestand it would be a breaking chage to modify the index naming logic, so i would like to use the Migrator().CreateIndex() method to add the desired composite unique index after the auto-migration has run.
The document you expected this should be explained
https://gorm.io/docs/migration.html
Expected answer
I would like to have know how to recreate the Composite Indexes mentioned in https://gorm.io/docs/indexes.html using the Migrator Interface
