pg - optional id for `generated always as identity`

[raduconst06]

Hello,

First I would like to congratulate on this very cool project.

I have a question regarding whether the id's should be optional when they are auto generated primary keys, as described below:

Given the following sql script migration

CREATE TABLE IF NOT EXISTS project (
	id INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY PRIMARY KEY,
	title varchar(100) NOT NULL
);

the following type for insertion is created:

/**
 * !!! This file is autogenerated do not edit by hand !!!
 *
 * Generated by: @databases/pg-schema-print-types
 * Checksum: l01RsxWnWb0RbxhBjInr7WGCBU8GDkc5dcPk8lJLY4D/dVPv4f/TudI3XAGryrwXVVcbziOtcbpetdYuUCvqFA==
 */

/* eslint-disable */
// tslint:disable

interface Project {
  id: number & {readonly __brand?: 'project_id'}
  title: string
}
export default Project;

interface Project_InsertParameters {
  id: number & {readonly __brand?: 'project_id'}
  title: string
}
export type {Project_InsertParameters}

Given the id is an auto-generated primary key I would expect to have something similar to the following type for Project_InsertParameters:

interface Project_InsertParameters (notice OptionalId) {
  id?: number & {readonly __brand?: 'project_id'}
  title: string
}

Why?
The value is generated by the database, I should not have to provide it.

Can you confirm if the current behavior is expected or if I am using the generated types wrong?

Thank you!
