我刚刚在我的 Mac OS Lion 机器上安装了 postgresql。我已经卸载并重新安装了
pg当我运行
psqlpsql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
跑步
which psql/usr/local/bin/psql我使用自制软件安装了 postgresql
这是 postgres 的

如何解决这个错误？谢谢！
首先尝试：
psql -h 本地主机
可能是客户端和服务器试图为 UNIX 域套接字使用不同的文件位置。您可以通过 tcp/ip 连接来避免这种情况。
pg_ctl -D /usr/local/var/postgres 启动
