   * _Query Result Mask._
   *
   * Binary mask that represents the result expected from queries.
   * It is used in the generic {@link Database.query query} method,
   * as well as method {@link Database.func func}.
   *
   * The mask is always the last optional parameter, which defaults to `queryResult.any`.
   *
   * Any combination of flags is supported, except for `one + many`.
   *
   * The type is available from the library's root: `pgp.queryResult`.
   *
   * @see {@link Database.query}, {@link Database.func}
