Как решить проблему при сохранении объекта в БД?

В БД PostgresSql была связь Таблица1-Таблица2. Я решил изменить ссылку одной таблицы на другую - дропнул внешний ключ, дропнул поле, создал новое поле и внешний ключ, теперь связь Таблица1 - Таблица3.

Сделал изменения в модели. Было:

public class Table1
{
    [Key]
    [Column("id")]
    public Guid Id { get; set; }
 
    [Column("id_table2")]
    public int TABLE2_Id { get; set; }
    public TABLE2 value { get; set; }
}

стало:

public class Table1
{
    [Key]
    [Column("id")]
    public Guid Id { get; set; }
 
    [Column("id_table3")]
    public int TABLE3_Id { get; set; }
    public TABLE3 value { get; set; }
}

Но теперь при сохранении объекта в БД, вылазит Exception такого типа, что он пытается вставить значение в поле "TABLE2", которого уже нет в БД:
