Comment (by Lev Lybin):

 I was looking for how to more elegant reduce joined query what author
 talk, and not found good solution, list all unneeded fields of joined
 table in 'defer' is not elegant solution. At this moment django doesn't
 has it. If look on how can customize prefetch_related with Prefetch() I
 have suggestion create e.g. 'Select' for select_related and use it like
 that: select_related('g') or select_related(Select('g').only('r', 't',
 's', 'u'))

Comment:

 I'm not in love with the proposed API. Giving `select _related()` the
 ability to fetch individual fields doesn't seem like a proper separation
 of concerns (that's what `only()` is for). You could raise a discussion on
 the DevelopersMailingList to see if consensus emerges about a more elegant
 solution.
