You are probably looking at

  https://pari.math.u-bordeaux.fr/dochtml/html/*

(which is specific to the development branch), instead of

  https://pari.math.u-bordeaux.fr/dochtml/html-stable/*

(which caters for *stable* released versions). Not sure where you got
the link but on our server, the two sets of documentations should be
carefully labelled as such, as in 

  https://pari.math.u-bordeaux.fr/doc.html

(Stable 2.9 vs. Testing 2.10)

All these functions are only available in pari-2.10, which is not yet
released. (But stay tuned: it's scheduled next week !)

If you want access to bleeding edge code in between releases, you can
either download a daily snapshot:

  https://pari.math.u-bordeaux.fr/pub/pari/mac/snapshots/

(for macOS), or sources from our git repository

  https://pari.math.u-bordeaux.fr/anongit.html

(which assumes you have a working development environment, a non-trivial
task on macOS)

Cheers,
