I see a few obvious differences between the tools, e.g. no setting of
checkpoint_segments in the online tool, but it looks like they've
more-or-less borrowed most of the rest of the config calculations out
of pgtune.
Honestly, it shouldn't be too hard to add support for more recent
Postgres versions to pgtune. A web UI is nifty for some purposes, but
as you noted, the nice aspect of pgtune is that you can run it on the
actual database server you are deploying and have it spit out a
suitable .conf file. I'm not sure if pgtune is still being maintained
much or at all these days (I still have an ancient PR hanging out
against it...) but it might be worthwhile to fork it and maintain the
project elsewhere if it needs an owner.
