That's a case where I would consider modifying
haskelldb-hdbc-postgresql, for example, to export an insertReturningId
or whatever, because some other engines don't support returning an ID,
and it wouldn't make sense to return Maybe Int or error for the ones
that don't support it. This way it's well-typed.
