postgresql 刪除庫的時候報錯database "temp_test_yang" is being accessed by other users

刪除庫的時候報錯

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

 

說明該temp_test_yang庫正在被人連接。解決方法是：

查詢出連接該數據庫的進程，並將其殺死(比較暴力)

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