[GENERAL] Is it good to have toast table for information schema table?

[AI Rumman]

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.
