ADM_AUDIT_TRAIL

ADM_AUDIT_TRAIL displays all standard audit trail entries. The audit information of GaussDB is mainly queried through the pg_query_audit function. This view exists in both PG_CATALOG and SYS schema. Only users with the AUDITADMIN attribute and the SELECT permission of ADM_AUDIT_TRAIL can view audit information. If separation of duties is disabled, users with the SYSADMIN attribute can also view audit information.

In a distributed system, the pg_query_audit function can only be used to query the audit information of the current node.
