Cannot create multiple PKs (mixin .increments with .primary)

I want to create a table basing on following MySQL dump:

CREATE TABLE `my_table` (
  `cmdId` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `deviceId` char(16) NOT NULL,
  `fnNumber` int(10) unsigned DEFAULT NULL,
  `chNumber` int(10) unsigned DEFAULT NULL,
  `cmd` varchar(50) DEFAULT NULL,
  `cmdDate` datetime DEFAULT NULL,
  `delivered` tinyint(1) DEFAULT NULL,
  PRIMARY KEY (`cmdId`,`deviceId`),
  KEY `deviceId` (`deviceId`),
  CONSTRAINT `tblcommands_ibfk_1` FOREIGN KEY (`deviceId`) REFERENCES `second_table` (`deviceId`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

My knex looks like:

knex.schema.createTable('my_table', function(t) {
    t.primary(['cmdId', 'deviceId']);
    t.increments('cmdId');
    t.string('deviceId', 16).notNullable().references('second_table.deviceId');
    t.integer('fnNumber').unsigned();
    t.integer('chNumber').unsigned();
    t.string('cmd96', 50);
    t.dateTime('cmdDate');
    t.boolean('delivered');
});

However there is a problem with primary keys. I get following error:

Error: Multiple primary key defined

I assume that increments method already creates PK and primary method creates another one which causes an error.

Is it possible to achieve this format of table ?

Or you can create de autoincrement column with

table.specificType('myid','serial');

(only for Postgresql)

But I think is much better table.increments() will create the PK only if i manually specify that with table.increments().primary()

Any news on this?
