在Postgres中杀死特定的SQL查询

Question

要杀死mysql中具有特定字符串的查询，我可以执行以下操作：

kill_string = 'LONG-QUERY'
cursor = self.conn.cursor()
cursor.execute("SHOW FULL processlist")
for _row in cursor.fetchall():
    _id = _row[0]
    _query = _row[-1] or ''
    if kill_string in _query:
        cursor.execute('KILL %s' % _id)

Postgres中的等效内容是什么？

Answer 1

非常相似，命令如下：

kill_string = 'LONG-QUERY'

cursor.execute("SELECT pid, query FROM pg_stat_activity")
for _row in cursor.fetchall():
    _id = _row[0]
    _query = _row[-1] or ''
    if kill_string in _query:
        cursor.execute('SELECT pg_terminate_backend(%s)' % _id)
