Rule names are now unique per-relation, rather than unique globally.
DROP RULE and COMMENT ON RULE syntax adds an 'ON tablename' clause, similar to TRIGGER syntaxes. To allow loading of existing pg_dump files containing COMMENT ON RULE, the COMMENT code will still accept the old syntax --- but only if the target rulename is unique across the whole database.
