How to convert string to boolean in laravel migration?

Question

I want to convert a field from string to boolean trying this code:

 public function up()
{
    Schema::table('users', function (Blueprint $table) {
        $table->boolean('email_permission')->change();
        $table->boolean('sms_permission')->change();
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::table('users', function (Blueprint $table) {
        //
    });
}

but i got the error below

Doctrine\DBAL\Driver\PDOException::("SQLSTATE[42804]: Datatype mismatch: 7 ERROR:  column 
"email_permission" cannot be cast automatically to type boolean
HINT:  You might need to specify "USING email_permission::boolean".")

this is original migration:

   public function up()
{
    Schema::table('users', function (Blueprint $table) {
        $table->string('email_permission')->nullable()->default('0');
        $table->string('sms_permission')->nullable()->default('0');
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::table('users', function (Blueprint $table) {
        $table->dropColumn('email_permission');
        $table->dropColumn('sms_permission');
    });
}

how can i change this field type from integer to boolean ?

Is the DB type postgresql? Does this help? https://stackoverflow.com/questions/41149554/default-for-column-xxxx-cannot-be-cast-automatically-to-type-boolean-in-postgr — nice_dev, Apr 04 '21 at 08:21
