Question

我通过自制软件安装postgresql9.4.5。在9.4.5之前，我使用9.3.9 macport，但我只想使用自制软件。所以我卸载9.3.9和macport并安装9.4.5 by homebrew。

我可以成功＆＃34; initdb / usr / local / var / postgres＆＃34;。但是，当我输入＆＃34; postgres -D / usr / local / var / postgres＆＃34;时，显示错误。

The error
LOG:  could not bind IPv6 socket: Address already in use
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
LOG:  could not bind IPv4 socket: Address already in use
HINT:  Is another postmaster already running on port 5432? If not, wait a few seconds and retry.
WARNING:  could not create listen socket for "localhost"
FATAL:  could not create any TCP/IP sockets

我想手动启动服务器 pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

但是，pg_ctl -D /usr/local/var/postgres status显示pg_ctl: no server running。

我确认了pg_hba.conf并显示

# IPv4 local connections:
host    all             all             127.0.0.1/32            trust

此外，当我输入psql时，会显示错误psql: FATAL: could not open relation mapping file "global/pg_filenode.map": No such file or directory

我需要做什么？请告诉我。

添加附言
我也试过ps aux | grep postgres

这表明某些进程处于活动状态。并且，2行显示macport pass。但是，我删除了/ opt / local文件夹我杀了这些进程，ps aux | grep postgres没有显示任何内容。所以，我试过postgres -D /usr/local/var/postgres。下次，显示

LOG:  database system was shut down at 2015-11-19 18:45:38 JST
LOG:  MultiXact member wraparound protections are now enabled
LOG:  database system is ready to accept connections
LOG:  autovacuum launcher started

并且，终端停止并且没有显示提示。所以我必须输入＆＃39; control + c＆＃39;

但是，我可以手动启动postgres。我做了这个命令pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start 我可以做psql命令。
