Is it good to have toast table for information schema table?

Hi,

Is it good to have toast table for information schema table? I am using Postgresql 8.4 and current state is:

select datname, datfrozenxid from pg_database;           

  datname  | datfrozenxid 

-----------+--------------

 template1 |   1462730397

 template0 |   1462741467

 postgres  |   1562754912

 jangles   |   1459615432

(4 rows)

select * from pg_class  where relfrozenxid  = 1459615432;

    relname     | reltoastidxid | relhasindex | relfrozenxid 

----------------+---------------+-------------+--------------

 pg_toast_11447 |         11451 | t           |   1459615432 

(1 row)

select 11447::regclass;                                  

            regclass             

---------------------------------

 information_schema.sql_features

(1 row)

Please advice.

Thanks.
