how to list privileges on the database object itself via SQL?

There appear to be a million ways to list the privileges on various database objects; tables, views, foreign tables, etc.  but for the life of me there doesn't appear to an analogous way to get permissions on the database objects themselves.

At the moment all that I've found is:

select has_database_privilege('role','db_name', 'CREATE') as can_create;
select has_database_privilege('role','db_name', 'CONNECT') as can_connect;
select has_database_privilege('role','db_name', 'TEMP') as can_temp;

 

Am I missing something?

Thanks,
