postgresql報錯:

　　psql: 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"?

1.可能是服務沒啟動，以下3中啟動方式：

　　（1） postmaster -D /usr/local/pgsql/data/　　（注意：這里的/usr/local/pgsql/data/ 是你的postgresql安裝路徑）

　　（2）postmaster -D /usr/local/pgsql/data/ > logfile 2>&1 &

　　（3）pg_ctl start -D /usr/local/pgsql/data/

2.可能是系統環境沒加psql:

　　用which psql回車找到psql路徑，用echo $PATH查看PATH中有沒有psql路徑，沒有的話就添加：方法如下：http://www.cnblogs.com/nightswatch/articles/4439776.html

3.還有問題的話：移步http://stackoverflow.com/questions/12472988/postgresql-error-could-not-connect-to-server-no-such-file-or-directory
