createMigration bug: if columns depending on other columns

[siggi-k]

Use case:
I added a column name_index which stores a tsvector generated from another column name (similar to issue #107).

LeadBankAccount.yaml

# LeadBankAccount:
title: LeadBankAccount
x-table: lead_bank_accounts
type: object

x-indexes:
  - gin:accountOwner_index

required:
  - id
  - accountOwner
  - accountOwner_index

properties:

  id:
    type: integer
    example: 12531
    readOnly: true

  accountOwner:
    type: string
    example: 'Lukas Sarfert'
    maxLength: 128

  accountOwner_index:
    type: string
    x-db-type: |
      tsvector GENERATED ALWAYS AS (
          to_tsvector('simple', coalesce(accountOwner, ''))
      ) STORED
    readOnly: true
    x-faker: false

m251023_130000_change_table_lead_bank_accounts.php

/**
 * Table for LeadBankAccount
 */
class m251023_130000_change_table_lead_bank_accounts extends \yii\db\Migration
{
    public function safeUp()
    {
        $this->db->createCommand('ALTER TABLE {{%lead_bank_accounts}} ADD COLUMN "accountOwner_index" tsvector generated always as (
    to_tsvector(\'simple\', coalesce(accountowner, \'\'))
) stored
 NOT NULL')->execute();
        $this->createIndex('lead_bank_accounts_accountOwner_index_gin_index', '{{%lead_bank_accounts}}', 'accountOwner_index', 'gin');
    }

    public function safeDown()
    {
        $this->dropIndex('lead_bank_accounts_accountOwner_index_gin_index', '{{%lead_bank_accounts}}');
        $this->dropColumn('{{%lead_bank_accounts}}', 'accountOwner_index');
    }
}

Problem with case sensitivity in column names coalesce(accountowner, \'\')) instead of coalesce(accountOwner, \'\')).

I have tried different variants in YAML such as:

  accountOwner_index:
    type: string
    x-db-type: |
      tsvector GENERATED ALWAYS AS (
          to_tsvector('simple', coalesce(accountOwner, ''))
      ) STORED
    readOnly: true
    x-faker: false

  accountOwner_index:
    type: string
    x-db-type: |
      tsvector GENERATED ALWAYS AS (
          to_tsvector('simple', coalesce("accountOwner", ''))
      ) STORED
    readOnly: true
    x-faker: false

  accountOwner_index:
    type: string
    x-db-type: |
      tsvector GENERATED ALWAYS AS (
          to_tsvector('simple', coalesce(\"accountOwner\", ''))
      ) STORED
    readOnly: true
    x-faker: false

Unfortunately, none of these attempts were successful.

How can I define a column name here so that the generated migration also contains an uppercase letter?
