+ * to the last row ID of the given @a reserve_pub in the reserve history table.
  *
  * @param cls the `struct PostgresClosure` with the plugin-specific state
  * @param reserve_pub public key of the reserve
+ * @param start_off maximum starting offset in history to exclude from returning
+ * @param etag_in up to this offset the client already has a response, do not
+ *                   return anything unless @a etag_out will be larger

  * @param[out] balance set to the reserve balance
  * @param[out] rhp set to known transaction history (NULL if reserve is unknown)
