Select @RelationId() - column not found

Issue type:

[ ] question [x] bug report [ ] feature request [ ] documentation issue

Database system/driver:

[ ] cordova [ ] mongodb [ ] mssql [ ] mysql / mariadb [ ] oracle [x] postgres [ ] cockroachdb [ ] sqlite [ ] sqljs [ ] react-native [ ] expo

TypeORM version:

[x] latest [ ] @next [ ] 0.x.x (or put your version here)

Steps to reproduce or a small repository showing the problem:

@Entity({ schema: 'public' })
export class OAuthCode {

  @PrimaryGeneratedColumn()
  id: number;

  @ManyToOne(type => OAuthClient)
  @JoinColumn({ name: 'client_id', referencedColumnName: 'clientId' })
  client: OAuthClient;

  @RelationId((code: OAuthCode) => code.client)
  clientId: string;
}

@Entity({ schema: 'public' })
export class OAuthClient {

  @PrimaryGeneratedColumn()
  id: number;

  @Index({ unique: true })
  @Column()
  clientId: string;
}

If i try to select explicitly relation id field like :

const oauthCode: OAuthCode = await this.codeRepository.findOne({
      select: [
       'clientId',
      ]
      where: {
        code: requestCode,
      },
    });

I got

{
    "code": 503,
    "inner": {},
    "message": "clientId column was not found in the OAuthCode entity.",
    "name": "server_error",
    "status": 503,
    "statusCode": 503
}

Why it’s not possible to select @RelationId() like regular @Column() ?

Thanks !
