Then I have a subsequent question.
Does the query
SELECT g_database_size('dbname');
take into account the storage space of the table pg_shdepend or not?
Regards
Horst

It does not. Nor does it include the other global tables, such as
pg_database, pg_authid, etc. To get the list of global tables and their
indexes, use:
select relname from pg_class where relisshared;
The size of the global tables and indexes, which don't count towards the
size of any individual database, can be obtained with
pg_tablespace_size('pg_global'). (All global tables must be in the
pg_global tablespace, and no other tables are allowed there.)

Yes, pg_database_size() includes all disk space used by the database i.e.
catalog tables or user data.
