I know ecto has Ecto.Adapters.SQL.to_sql(:all, repo, Post) which will give you raw sql for any query. But I want to inspect/debug an update which is giving me ** (Postgrex.Error) ERROR 21000 (cardinality_violation) more than one row returned by a subquery used as an expression . is there a way I can inspect changeset update inside test cases ie what query exactly was generated by ecto(why I wanna debug because inserting directly to postgres is working perfectly fine)

#Ecto.Changeset<
  action: nil,
  changes: %{
    infection_rxs: [
      #Ecto.Changeset<action: :replace, changes: %{}, errors: [],
       data: #HaiData.InfectionRx<>, valid?: true>,
      #Ecto.Changeset<
        action: :insert,
        changes: %{infection_id: 55, rx_id: 155},
        errors: [],
        data: #HaiData.InfectionRx<>,
        valid?: true
      >
    ]
  },
  errors: [],
  data: #HaiData.Infection<>,
  valid?: true
>

and by running Repo.update(changeset), I get

(Postgrex.Error) ERROR 21000 (cardinality_violation) more than one row returned by a subquery used as an expression

which is really strange for an update
