Обсуждение: How to identify all storage in a schema

PostgreSQL 9.3
Is there a query one can run that will give you a total storage for all objects (tables, indexes, etc) associated with
aparticular schema? 

Thanks for your assistance.

  select table_schema,
         sum(pg_total_relation_size(table_schema|| '.' ||table_name))
  from information_schema.tables
  where table_schema not in ('information_schema', 'pg_catalog')
  group by table_schema;

Of for just a single schema:

  select sum(pg_total_relation_size(table_schema|| '.' ||table_name))
  from information_schema.tables
  where table_schema = 'foobar';

There are other functions to retrieve the table or database sizes:
