The only ones that are not covered from what I see are fillfactor and
parallel_workers.
The settings that cover items in postgresql.conf have defaults shown here:
https://www.postgresql.org/docs/current/runtime-config.html
As example the default for:
vacuum_truncate, toast.vacuum_truncate
Per-table value for vacuum_truncate parameter.
can be found here:
https://www.postgresql.org/docs/current/runtime-config-vacuum.html#GUC-VACUUM-TRUNCATE

fillfactor: The fillfactor for a table is a percentage between 10 and 100.
100 (complete packing) is the default.
parallel_workers: If not set, the system will determine a value based on
the relation size.
I don't think including the algorithm for parallel_workers would be
appropriate for the documentation.
Hence, both are indeed "covered".
