Function create_record_with_executor 

pub async fn create_record_with_executor<'e, E, M, PK, I>(
    executor: E,
    policy_pool: &PgPool,
    descriptor: &'static ModelDescriptor<M, PK>,
    input: I,
    ctx: &CratestackContext,
) -> Result<M, CratestackError>
where
    E: Executor<'e, Database = Postgres>,
    I: CreateModelInput<M>,
    for<'r> M: Send + Unpin + FromRow<'r, PgRow> + Serialize,

Passing a pool as policy_pool while executor is a transaction takes a second connection; prefer the builder’s run_in_tx.
