server closed the connection unexpectedly This probably means the server terminated abnormally bef

1.在网上可能找的方案如下：

try:
    cur.execute(sql_1)
    conn.commit()
except Exception as e:
    print(e)
    print("jira数据无法同步至数据库")
    conn = pg_conn()
    cur = conn.cursor().execute(sql_1)
    conn.commit()

出错以后再次进行链接，也许可以解决问题。但是直接pass掉
