$du -h $MY_DATA/base/$BASE_OID/ returns 162GB but when I execute this query:

|I obtain 80GB in total_table_size (half of my database), where are
missing data at?
First of all you are using pg_statio_user_tables which does not count
system tables.
Second pretty sure the use of current_schema is limiting the results to
only one schema in the database.

Well you can always look in $DATA directly. The database will be
under $DATA/base/<db oid>.
You can find the <db oid> like this:
select oid, datname from pg_database where datname='<db name>';
