-gsample- will only produce appropriate PPS samples if you specify
sampling with replacement (which is the approximation you would have
to make at the analysis stage, anyway). PPS sampling without
replacement is far more complicated, and if the phrase "Rao-Sampford
algorithm" does not ring a bell, you will end up with wrong sampling
