#26
In my solution we don't need to make SqlDB monad type polymorphic and change all existing queries.
Instead I use existential quantification:

data SqlDBEnv = forall m.
  Finalize m =>
  SqlDBEnv
  { currentTime :: UTCTime,
    actions :: m ()
  }

How did you test it?

Tested locally. Tested transaction inside of transaction. All finalizer actions worked as expected.
