My original way used the source tree, but Michael thought it would be an issue
for "installcheck" where the config may not be available.

This is what I had written:
-- test that GUCS are in postgresql.conf
SELECT lower(name) FROM tab_settings_flags WHERE NOT not_in_sample EXCEPT
SELECT regexp_replace(ln, '^#?([_[:alpha:]]+) (= .*|[^ ]*$)', '\1') AS guc
FROM (SELECT regexp_split_to_table(pg_read_file('postgresql.conf'), '\n') AS
ln) conf
WHERE ln ~ '^#?[[:alpha:]]'
ORDER BY 1;
