Naming conflicts when referencing multiple time the same table
### Summary

Lets say I have a table called "transaction" with 2 columns: "sender_account_id" and "receiver_account_id".
Both of the columns reference the same table called "account".
The problem is that postgraphile throws error saying that it has a naming conflict.
How can I tell postgraphile to call one of the references that he creates in a different way so the names wont be the same?

Its important to note that I do have to use the `references` syntax from postgres to really create that foreign key to inforce data integrity, so using the `@foreignKey` wont be relevant here unless we can combine both of the approaches in some way. 
Thanks!
