Ok, thanks for the clarification :-)

The 'problem' is that as a developer with advanced knowledge of the
postgres internals, you see a table as a group of relations (toast,
indexes, toast relation's index, etc)

A 'normal' user only sees a table and its indexes and this user
misinterpret the use of the function "pg_relation_size() when it reads
in the documentation "pg_relation_size(): Disk space used by the table
or index ... "
