 * @param cls the `struct PostgresClosure` with the plugin-specific state
 * @param commitment the commitment with all parameters
 * @param now current time (rounded)
 * @param[out] found set to true if the reserve was found
 * @param[out] balance_ok set to true if the balance was sufficient
 * @param[out] reserve_balance set to the original reserve balance (at the start of this transaction)
 * @param[out] age_ok set to true if no age requirements are present on the reserve
 * @param[out] required_age if @e age_ok is false, set to the maximum allowed age when withdrawing from this reserve
 * @param[out] reserve_birthday if @e age_ok is false, set to the birthday of the reserve
 * @param[out] conflict set to true if there already is an entry in the database for the given pair (h_commitment, reserve_pub)
