  • [Ecto.Query] Make sure the :prefix option in :from/:join also cascades to subqueries
  • [Ecto.Query] Make sure the :prefix option in :join also cascades to queries
  • [Ecto.Query] Use database returned values for literals. Previous Ecto versions knew literals from queries should not be discarded for combinations but, even if they were not discarded, we would ignore the values returned by the database
