Issue while trying to create records and remove the RETURNING statement. about postgres HOT 1 CLOSED

Copying my Stackoferflow question, where I wrote with a simple code to demo the problem:

I'm using go-gorm with a postgres 11 DB and facing an issue where I need to remove the RETURNING clause entirely when creating records (that statement seems to be included by default). I just want to insert records and get nothing back, except for errors.
I have some complex relations on the database that won't support RETURNING statements, so when I try to insert like this: (made code simpler for brevity)

type Cargo struct {
	Id   int64 `gorm:"primaryKey"`
	Name string
}
dsnString := fmt.Sprintf("host=%s ...") 
db, _ := gorm.Open(postgres.New(postgres.Config{DSN: dsnString}), &gorm.Config{})

cargo := Cargo{Name: "test"}
db.Create(cargo)

I get the error "ERROR: cannot perform INSERT RETURNING on relation X".

I tried creating the db connection with the parameter WithoutReturning: true:

db, _ := gorm.Open(postgres.New(postgres.Config{DSN: dsnString, WithoutReturning: true}), &gorm.Config{})

But then when I try db.Create(cargo) I get a different error: "LastInsertId is not supported by this driver". It seems to be still trying to get the last inserted id anyway.

In go-pg I could use db.Model(x).Returning("null").Insert(cargo) but I couldn't find a way to do it with go-gorm. Any help is greatly appreciated.
