Documentation for `makePgService({adaptorSettings})` appear to be outdated
### 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The documentation at https://postgraphile.org/postgraphile/next/config#adaptorsettings is outdated.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`.
