func main() {        
        type ID int64
	type TIME time.Time
	type BYTES []byte
	type TypeAlias struct {
		ID
		TIME  `gorm:"column:ftime;type:timestamptz"`
		BYTES `gorm:"column:fbytes;type:bytea"`
	}

	db, err := gorm.Open(postgres.New(postgres.Config{

	})
	if err != nil {
		log.Fatal(err)

	al := &TypeAlias{
		ID:    2,
		TIME:  TIME(time.Now()),
		BYTES: []byte{1, 2, 3},
	}

	if err := db.AutoMigrate(al); err != nil {
		t.Fatal(err)
