postgresql 怎么查某事务正执行的SQL语句

SELECt
procpid,
start,
now() - start AS lap,
current_query
FROM
(SELECt
backendid,
pg_stat_get_backend_pid(S.backendid) AS procpid,
pg_stat_get_backend_activity_start(S.backendid) AS start,
pg_stat_get_backend_activity(S.backendid) AS current_query
FROM
(SELECT pg_stat_get_backend_idset() AS backendid) AS S
) AS S
WHERe
current_query <> ''
ORDER BY
lap DESC;

procpid：进程id
start：进程开始时间
lap：经过时间
current_query：执行中的sql
怎样停止正在执行的sql
SELECT pg_cancel_backend(进程id);
或者用系统函数
kill -9 进程id;
