在 OSX 上为 PostgreSQL 创建数据库和客户端连接

Question

如何启动 PostgreSQL 数据库并在终端中连接客户端？

我在用 brew 安装 postgreSQL 后试过这个。

which psql

结果：

/usr/local/bin/psql

然后我尝试启动数据库：

pg_ctl init -D /usr/local/bin/psql

给出：

The files belonging to this database system will be owned by user "matt".
This user must also own the server process.

The database cluster will be initialized with locale "en_AU.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

initdb: could not access directory "/usr/local/bin/psql": Not a directory
pg_ctl: database system initialization failed

Answer 1

来自 PostgreSQL pg_ctl 文档：

-D datadir

--pgdata datadir

Specifies the file system location of the database configuration files. If this is omitted, the environment variable PGDATA is used.

您正在将 pgsql 可执行文件指定为您的数据目录。

Answer 2

您必须先创建一个数据目录，并在-D后输入它的名字。假设您创建的数据目录是 /usr/local/bin/psql，那么您的初始化命令将是

pg_ctl init -D /usr/local/bin/psql/data
