Type Conflict 
I have two types inside the same schema with the same field names as below :

```
CREATE TYPE stateless_service_identity_anonymous.forgot_password_result AS (
	status text,
	error text,
	message text);
```

```
CREATE TYPE stateless_service_identity_anonymous.establish_session_result AS (
	status text,
	error text,
	message text,
	"data" mdgy_session);
```

When restarting postgraphile I get the error below: 
```
> Error: A type naming conflict has occurred - two entities have tried to define the same type 'ForgotPasswordPayload'.…
Recoverable error occurred; use envvar 'DEBUG="graphile-build:warn"' for full error (see: https://graphile.org/postgraphile/debugging )
> Error: A type naming conflict has occurred - two entities have tried to define the same type 'EstablishSessionPayload'.…
Recoverable error occurred; use envvar 'DEBUG="graphile-build:warn"' for full error (see: https://graphile.org/postgraphile/debugging )

```

Can you help me out here. 

The only thing that I can observe is that the schema where these two datatypes are is the same and also the field names are same. Could this be a problem.
