Is it possible to create an index concurrently in Postgres using GORM?

Question

Postgress allows creating indexes with the concurrently option (https://www.postgresql.org/docs/9.1/sql-createindex.html).

This allows building the index without locking the tables. Is it possible to allow gorm to use this option?

On the other end, what is the default behavior of AutoMigrate() will it wait until the index is successfully built before returning?

The feature has been implemented and now is possible to add the CONCURRENTLY option via the struct metadata:

// PostgreSQL option
type User struct {
  Name string `gorm:"index:,option:CONCURRENTLY"`
}
