我正在尝试使用 shell 脚本自动执行数据库创建过程，并且我在将密码传递给 psql.这是shell脚本中的一些代码:

有一个 ~/.pgpass 文件也很方便，以避免经常输入密码.有关详细信息，请参阅第 30.13 节.

此文件应包含以下格式的行:

主机名:端口:数据库:用户名:密码

将使用第一行中与当前连接参数匹配的密码字段.

I am trying to automate database creation process with a shell script and one thing I've hit a road block with passing a password to psql. Here is a bit of code from the shell script:

psql -U $DB_USER -h localhost -c"$DB_RECREATE_SQL"

How do I pass a password to psql in a non-interactive way?

解决方案

From the official documentation:

It is also convenient to have a ~/.pgpass file to avoid regularly having to type in passwords. See Section 30.13 for more information.

...

This file should contain lines of the following format:

hostname:port:database:username:password

The password field from the first line that matches the current connection parameters will be used.
