Table size does not include toast size

Hello

I wonder why the function pg_relation_size(text) does not take into
account the space used by toast data in a table when returning the space
used by the table.

As an administrator I would expect pg_total_relation_size() to return
data+toast+indexes and pg_relation_size() to return data+toast.

Is this a deliberate decision? Could we change this behavior in the future?

We are using a 8.3 database.

Thanks in advance.
regards,
