It works exactly as documented: pg_total_relation_size(regclass) - Total disk space used by the specified table, including all indexes and TOAST data It says nothing about including partitions. If we change this, then we certainly need to update the documentation (that might be a good idea if we decide not to update this). Personally, I'm -1 on including partitions, because then you can no longer expect that the sum of pg_total_relation_size(regclass) across all relations in the database will equal the size of the database itself. Partitions will be counted a number of times equal to their depth in the partitioning hierarchy. However, I understand that I might get outvoted. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
