postgresql 删除库的时候报错database "temp_test_yang" is being accessed by other users

删除库的时候报错

ERROR: database "temp_test_yang" is being accessed by other users
DETAIL: There are 4 other sessions using the database.

 

说明该temp_test_yang库正在被人连接。解决方法是：

查询出连接该数据库的进程，并将其杀死(比较暴力)

select pg_terminate_backend(pid) from pg_stat_activity where DATNAME = 'temp_test_yang';
