Gorm Add/Delete a primaryKey not working for add new column or alter existing column

gorm.io/gorm v1.22.5

db: mysql

1、Delete primary key do NOT work

type TestB struct {
    AColumn string `gorm:"column:a;"  
    BColumn int64  `gorm:"primaryKey;column:b;"  
    CColumn int64  `gorm:"primaryKey;column:c;"  
}

err := db.Debug().Table("table_b").AutoMigrate(&TestB{})

will create table_b with create primary key

PRIMARY KEY (`b`,`c`)

I modify CColumn tag to : gorm:"column:c;" to update table primary key to PRIMARY KEY (`b`), but it NOT working.

type TestB struct {
    AColumn string `gorm:"column:a;"  
    BColumn int64  `gorm:"primaryKey;column:b;"  
    CColumn int64  `gorm:"column:c;"  
}

err := db.Debug().Table("table_b").AutoMigrate(&TestB{})  
err = db.Debug().Table("table_b").Migrator().AlterColumn(&TestB{}, "CColumn")

(primaryKey also is b,c NOT b)

2、Add primary key do NOT work

type TestB struct {
    AColumn string `gorm:"column:a;"`
    BColumn int64  `gorm:"primaryKey;column:b;"`
}

err := db.Debug().Table("table_b").AutoMigrate(&TestB{})

with create primary key PRIMARY KEY (`b`)

add a new CColumn to update primaryKey to b,c

type TestB struct {
    AColumn string `gorm:"column:a;"`
    BColumn int64  `gorm:"primaryKey;column:b;"`
    CColumn int64  `gorm:"primaryKey;column:c;"`
}

err := db.Debug().Table("table_b").AutoMigrate(&TestB{})
err = db.Debug().Table("table_b").Migrator().AddColumn(&TestB{}, "CColumn")`

Also NOT woking (primaryKey also is b, not b,c)

I meet the same problem with postgresql. When I change the primary key settings, AutoMigrate doesn't effect.
