How to use NamingStrategy.IdentifierMaxLength in postgres driver

[alidevhere]

Describe the feature

NamingStrategy.IdentifierMaxLength has been added in gorm, which allows to override max length of 64. How to make use of this in postgres driver to change it to 63.
@jinzhu
i can only think of it like this :

import (
	"gorm.io/driver/postgres"
	"gorm.io/gorm"
	s "gorm.io/gorm/schema"
)

func main() {

	db, err := gorm.Open(postgres.New(postgres.Config{
		DSN:                  "host=localhost user=gorm password=gorm dbname=gorm port=9920 sslmode=disable TimeZone=Asia/Shanghai", // data source name, refer https://github.com/jackc/pgx
		PreferSimpleProtocol: true,                                                                                                  // disables implicit prepared statement usage. By default pgx automatically uses the extended protocol
	}), &gorm.Config{NamingStrategy: s.NamingStrategy{IdentifierMaxLength: 63}})

}
