postgresql - start on mac - `pg_ctl` not working
提问by Lucy Weatherford
I want to use the pre-installed postgresql on my local machine (mac os 10.7.5), when I run which psqlI find it (in /usr/bin/psql), but then running
我想在我的本地机器（mac os 10.7.5）上使用预装的 postgresql，当我运行时which psql我发现它（在/usr/bin/psql），但然后运行
pg_ctl -D /usr/bin/psql -l /usr/bin/psql/server.log start
results in:
结果是：
-bash: pg_ctl: command not found
How can I start/use my postgresql database? do I need to install it (with say Homebrew) or can I use the pre-installed one on my mac?
I also tried using the initdbcommand (initdb /usr/bin/psql -E utf8) and also go tthe same message: -bash: initdb: command not found.
如何启动/使用我的 postgresql 数据库？我需要安装它（比如 Homebrew）还是我可以在我的 mac 上使用预装的？我也尝试使用initdb命令 ( initdb /usr/bin/psql -E utf8) 并且也得到相同的消息：-bash: initdb: command not found.
Also, is this psqlthe same as postgres? (I tried which postgresand got nothing)
另外，这psql与postgres? （我试过which postgres了，一无所获）
Update: I'm using psqlcommands in the command line, but am getting there the following message (for psql -land psql -afor instance):
更新：我使用psql的命令在命令行，但我越来越有下列消息（psql -l及psql -a为例）：
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

OS X ships with the command line client (for interacting with postgres databases) not the server.
OS X 附带命令行客户端（用于与 postgres 数据库交互）而不是服务器。
You need to install the server.
您需要安装服务器。
Check the postgres siteor grab the postgres.app
