Documentation for `makePgService({adaptorSettings})` appear to be outdated

[FelixZY]

Summary

The documentation at https://postgraphile.org/postgraphile/next/config#adaptorsettings is outdated. Specifically, adaptorSettings, poolConfig and superuserConnectionString (those are the once I've tried, can't speak for the rest) are no longer available in 5.0.0-beta.26.
