PostgreSQL 列举和停止执行中的 sql

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; PostgreSQL SELECT procpid, start, now() - start AS lap, current_query FROM

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;
