SUMMARY_STAT_SYS_TABLES

Displays the status statistics of all system catalogs in the pg_catalog, information_schema, and pg_toast schemas in the cluster. The statistics are used on CNs and include data on CNs and DNs. The status information in the system catalog on each node is summed up. The timestamp column is not summed up and only the latest value of this column on all nodes is used.
