我似乎陷入了两个操作之间，两者都是<li><a href="#">sampletest1</a></li>

用来切换pg_upgrade主要版本，而PostgreSQL是用来控制pg_ctl的当前邮政局长控制权的。

There seems to be a postmaster servicing the old cluster.
Please shutdown that postmaster and try again.

，但没有解决任何问题。文件说我可以使用/usr/local/var/postgres/postgresql.pid关闭邮局局长，但这不起作用：
pg_ctl因此，我不能在不关闭邮局主管的情况下升级该版本，并且关闭邮局主管需要初始化新版本。我被抓了关于如何使[Sun Dec 30 09:44 rich@HQ ~] pg_ctl --pgdata=/usr/local/var/postgres start -m fast
