GV_SESSION

GV_SESSION displays information about all current sessions. Only administrators can access this view. Common users can access the view only after being authorized. This view exists in both the PG_CATALOG and SYS schemas. When the thread pool is enabled (enable_thread_pool is set to on), all session information is displayed. When the thread pool is disabled (enable_thread_pool is set to off), the sessions connected by users are not displayed. For details about the columns, see Table 1.
