Log message:
    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.
