PGXC_GET_STAT_ALL_TABLES

PGXC_GET_STAT_ALL_TABLES displays information about insertion, update, and deletion operations on tables and the dirty page rate of tables. Before running VACUUM FULL to a system catalog with a high dirty page rate, ensure that no user is performing operations on it. This view is a new feature of GaussDB, and will not collect statistics on insertion, update, and deletion operations in earlier versions. You are advised to run VACUUM FULL to tables (excluding system catalogs) whose dirty page rate exceeds 30% or run it based on service scenarios. Only users with the system admin or monitor admin permission can view the information. For details about the columns, see Table 1.
