无法在mac os x上重启postgres

Question

我无法在Mac OS X上重新启动postgres服务器.我该如何解决这个问题？

试过两种方式:

pg_ctl restart返回:

pg_ctl: PID file "usr/local/var/postgres:/postmaster.pid" does not exist
Is server running?
starting server anyway
pg_ctl: could not read file "usr/local/var/postgres:/postmaster.opts"

服务器不会重新启动

pg_ctl -D/usr/local/var/postgres restart导致:

   pg_ctl: PID file "/usr/local/var/postgres/postmaster.pid" does not exist
   Is server running?
   starting server anyway
   server starting
   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.
   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.
   WARNING:  could not create listen socket for "*"
   FATAL:  could not create any TCP/IP sockets

1 - 您的data目录可能有误.确保使用正确的路径.

2 - 如果您安装了多个postgres,则需要指定pg_ctl要使用的postgres .

我手动安装了postgres 9.2,这是我如何启动它:

/Library/PostgreSQL/9.2/bin/pg_ctl -D /Library/PostgreSQL/9.2/data start

我通过HomeBrew安装了postgres 9.1,以下是它的启动方式:

/usr/local/Cellar/postgresql/9.1.5/bin/pg_ctl -D /usr/local/var/postgres-9.1.5 start
