Join() being ignored when using Delete()

Hello. I am wanting to create a SQL statement that involves a DELETE and JOIN keyword. Here is a small example: ```sql DELETE FROM role_refs JOIN roles as role ON role.id = id WHERE role.name = 'Admin' # role_ref and role is a many-to-one relationship; a role_ref can be matched with a single role at most. ``` Using go-pg, I'm using this code to mirror the above statement: ```go Model((*RoleRef)(nil)). Join(`JOIN roles as role ON role.id = id`). Where(`role.name = ?`, "Admin"). Delete() ``` The table and column names don't really matter, but rather it's using both Join() and Delete(). However, when I execute the go-pg code, the assembled SQL statement is missing the JOIN statement completely: ```sql DELETE FROM role_refs WHERE role.name = 'Admin' ``` I also tried replacing `Join()` with `Relation()` but there is no JOIN keyword in the resulting SQL either. Is this a bug?
