Comment (by mrts):
Right you are, `select_related('a', 'b').query.as_sql()` looks correct:
{{{
>>> C.objects.all().only('name', 'a', 'b', 'a__name',
'b__name').select_related('a', 'b').query.as_sql()
('SELECT "only_breakage_c"."id", "only_breakage_c"."name",
"only_breakage_c"."a_id", "only_breakage_c"."b_id",
"only_breakage_a"."id", "only_breakage_a"."name",
"only_breakage_b"."id", "only_breakage_b"."name"
FROM "only_breakage_c"
LEFT OUTER JOIN "only_breakage_a" ON ("only_breakage_c"."a_id" =
"only_breakage_a"."id")
INNER JOIN "only_breakage_b" ON ("only_breakage_c"."b_id" =
"only_breakage_b"."id")',
())
}}}
Doesn't affect the behaviour though, problems 1-3 remain.
