PG_STAT_ACTIVITY T where T.DATNAME='数据库名'and T.WAIT_EVENT_TYPE='Lock'; 三、通过pid解锁死锁信息 selectPG_CANCEL_BACKEND('pid'); ——— 原文链接:https://blog.csdn.net/qq_41256881/article/details/122461785 四、杀死进程: 进入linux kill xxxx...
select pg_cancel_backend( '进程pid');该语句可以把锁住的进程杀掉。 通过sql语句拼装可以方便的把所有进程号封装起来,进而进行批量解锁select 'select pg_cancel_backend( '''|| pid ||''');' pid from pg_stat_activity where datname='auto_2012_oracle_yz1' and wait_event_type = 'Lock'; 查询后...
首先,你需要确定要杀死的进程ID(PID)。这可以通过查询 pg_stat_activity 系统视图来完成,该视图包含了当前所有活动的会话信息。 sql SELECT pid, usename, datname, query, state FROM pg_stat_activity WHERE state = 'active'; -- 只显示活动状态的进程 执行上述查询后,你将看到一个包含多个列的结果集,其...
from pg_stat_activity where backend_type='client backend' group by rollup(1); 上面的语句就是来对postgresql 当前PG中的active 和 idle之间的连接进行比对。 如果想自动的KILL 一些比较过分的长transaction WITH inactive_connections AS ( SELECT pid, rank() over (partition by client_addr order by backen...
再根据上面查出来的pid去表pg_stat_activity查询一下该锁对应的SQL语句: select usename,current_query ,query_start,procpid,client_addr from pg_stat_activity where procpid=17509; 如下: usename | current_query | query_start | procpid | client_addr ...
通过上面查到的pid,在操作系统上ps -ef |grep pid查看当前连接的状态,然后kill -9 pid杀掉该连接。 代码语言:javascript 复制 postgres=# select pid,query_start,state,query from pg_stat_activity where state='active';pid|query_start|state|query---+---+---+---5001|2019-08-1312:45:16.652909+0...

查看死锁: SELECT pid, usename, datname, query, state, query_start, backend_start, backend_xid, backend_xmin FROM pg_stat_activity WHERE state = 'active' AND wait_event_type = 'Lock'; kill死锁: SELECT pg_cancel_backend(2016742);
