Enum type not working in postgres

Issue type:

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

Database system/driver:

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

TypeORM version:

[x] latest [ ] @next [ ] 0.2.0 (or put your version here)

Steps to reproduce or a small repository showing the problem:

type Action =
    'add' |
    'update' |
    'delete';
@Entity()
export class DatasourceAction {

    @PrimaryColumn()
    id: string;

    @Column({ name: 'name', type: 'text', unique: true })
    name: string;

    @Column({ name: 'action', type: 'enum', enum: ['add', 'update', 'delete'] })
    action: Action;
}

The SQL quarries executed are as follows

CREATE TYPE "test"."datasource_action_action_enum" AS ENUM('add', 'update', 'delete')
ALTER TABLE "test"."datasource_action" ADD "action" "datasource_action_action_enum" NOT NUL

and it errors with type “datasource_action_action_enum” does not exist

I think the the ALTER TABLE query should have been as follows. ALTER TABLE “test”.“datasource_action” ADD “action” “test”.“datasource_action_action_enum” NOT NUL

I hit the same problem

    @Column({
        type: "enum",
        enum: Gender,
        default: Gender.NotAvailable,
    })
    public gender!: Gender;

Gender enum class

export enum Gender
{
    Male = "male",
    Female = "female",
    Other = "other",
    NotAvailable = "n/a",
}

@pleerock I added all the previous enum tests with external schema as part of the PR, I also used this by manually patching typeorm in prod, let me know how I can assist to move this forward.
