我按照http://xadmin.info/?p=284中给出的说明安装了postgresql
# pg_ctl -D /var/lib/pgsql/data -l pglog.log start
server starting
postgres@linux-p0pl:~> psql
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"?
我不知道为什么我在服务器启动时出现此错误…有人可以请帮助.
我的pglog.log文件显示以下输出：
2013-02-06 19:43:39 GMT FATAL: lock file "postmaster.pid" already exists
