通过查询结果,可以知道,有一条alter 修改这个表的名字的ddl语句 一直卡在那里,导致后面的select都是卡住的 经过和研发确认,确实是执行了表名的修改的动作。 3.2 杀掉阻塞进程 找到了阻塞的进程,直接干掉 SELECT pg_terminate_backend ( 5927 ); 括号里的5927是阻塞进程的ID。 这个进程被杀掉之后,查询的语句执行...
select xact_start, query_start, backend_start, state_change, state from pg_stat_activity where pid in (70334); 4.4 行琐问题解决 通过KILL会话即可解决行琐问题 select pg_terminate_backend(67712); 随后观察到会话2中的update执行成功 五、结论 pgrowlocks是一个强大的工具,它为PostgreSQL的锁管理提供了...

可以使用pg_terminate_backend函数来终止连接。 回滚事务:如果存在未完成的事务,可以尝试回滚这些事务,然后再执行重命名操作。可以使用ROLLBACK语句来回滚事务。 如果以上方法仍然无法解决问题,建议参考PostgreSQL官方文档或向PostgreSQL社区寻求帮助。 腾讯云提供了PostgreSQL数据库的云服务,称为TencentDB for PostgreSQL。它提供...
pg_signal_backend (Pg 9.6+) This is again very simple, basically gives user ability to runpg_cancel_backend()andpg_terminate_backend()functions, for backend that don't belong to the user. So, normally, any user canpg_cancel_backend()orpg_terminate_backend()to any backend that is logged...
CREATE TABLE tbl AS (SELECT (row_number() over())::integer "id", "col" FROM tbl2) Code is getting stuck (cursor.execute never returns), killing the transaction with pg_terminate_backend removes the query from the server, but the code is not released. Yet in this case, the target ...
+1, we should call it "dumb" :) Not accepting new connections with "the database system is shutting down" makes it even worse -- it means you can't log in to the server to inspect who's querying it or call pg_terminate_backend() on them. I couldn't find any past discussions ...
如果会话空闲，则pg_stat_activity显示该会话中最后执行的语句。所以这仅仅意味着所有这些会话都使用roll...
