只列出了些和 stop 相关的
pg_ctl stop -m smart
-m选项可以选择三种不同的关闭方法
pg_ctl stop -m smart
1
SIGTERM "Smart"模式等待所有客户端断开连接以及任何在线备份结束。如果该服务器是热备，一旦所有的客户端已经断开连接，恢复和流复制将被终止。
pg_ctl stop -m fast
pg_ctl stop -m fast
1
SIGINT "Fast"模式（默认）不会等待客户端断开连接并且将终止进行中的在线备份。所有活动事务都被回滚并且客户端被强制断开连接，然后服务器被关闭。
pg_ctl stop -m immediate
pg_ctl stop -m immediate
1
SIGQUIT "Immediate"模式将立刻中止所有服务器进程，而不是做一次干净的关闭。这将导致下一次重启时进行一次崩溃恢复。
