Bug reference: 15245
Logged by: Mahadevan Ramachandran
Email address: mahadevan(at)rapidloop(dot)com
PostgreSQL version: 10.4
Operating system: any
Description:
The system view pg_catalog.pg_stat_all_tables (and therefore also
pg_catalog.pg_stat_user_tables) do not list partition master tables (CREATE
TABLE ... PARTITION BY ..).
This is because it only includes rows from pg_class with relkind IN ('r',
't', 'm') (as defined in src/backend/catalog/system_views.sql).
IMHO, it should also include rows with relkind = 'p'.
