Looks like insert() does not return foreign keys. We could eventually
call findMany after but it seems that's what save() is doing so I'm
replacing insert with save.
```typescript
/**
* Flag to determine whether the entity that is being persisted
* should be reloaded during the persistence operation.
*
* It will work only on databases which does not support RETURNING / OUTPUT statement.
* Enabled by default.
*/
reload?: boolean;
```
Note: save() also does an upsert by default with no way to configure
that so if we want to keep that behaviour we will need to add a check
before
```typescript
if (args.upsert) {
const existingRecords = await repository.findBy({
id: Any(args.data.map((record) => record.id)),
});
...
```
