ADM_AUDIT_SESSION

ADM_AUDIT_SESSION displays all audit trail records concerning CONNECT and DISCONNECT. The audit information of GaussDB is mainly obtained through the pg_query_audit function. This view exists in both PG_CATALOG and SYS schema. Only users with the AUDITADMIN attribute can view audit information. The action_name column of GaussDB is inconsistent with the audit action of database ORA, and the transactionid column is consistent with the type of transactionid data in database ORA.
