And SELECT relnamespace::regnamespace::text, relname FROM pg_class WHERE
relkind='f'; tells you all of the foreign tables.

Thus, this (untested) query generate all of the DROP FOREIGN TABLE statements:
SELECT format('DROP FOREIGN TABLE IF EXISTS %I.%I RESTRICT;'
              , relnamespace::regnamespace::text, relname)
FROM pg_class WHERE relkind='f'
ORDER BY relkind;
