title: QueryFailedError: the column "price" contain null values - TypeORM - PostgreSQL
body: <p>I've created a simple table:</p>
  <pre><code>import { Column, Entity, PrimaryGeneratedColumn } from &quot;typeorm&quot;
  
  @Entity()
  export class Test {
      @PrimaryGeneratedColumn()
      public id!: number
  
      @Column({ nullable: false })
      public name!: string
  
      @Column({ nullable: false, type: &quot;float&quot; })
      public price!: number
  }
  </code></pre>
  <p>I generate the migration and run it also. When I have no data in the database and I run the server it succeed. But when I add 1 row in the database and I run it again it appears the following error:</p>
  <p><code>QueryFailedError: the column «price» contain null values</code></p>
  <p>The databse definetely has the row with all the data. I tried a lot of cases and none of them was correct.</p>
  <p>Has anybody some idea for it?</p>
