在命令中使用-w: psql -h localhost -p 5432 -U user -w

这也适用于其他postgresql cliis，例如你可以在非交互模式下运行pgbench。

export PGPASSWORD=yourpassword
/usr/pgsql-9.5/bin/pgbench -h $REMOTE_PG_HOST -p 5432 -U postgres -c 12 -j 4 -t 10000 example > pgbench.out 2>&1 &

你可以在脚本的开头添加这个命令行:

export PGPASSWORD="[your password]"

我发现，即使你定义了PGPASSWORD变量，psql显示密码提示，但你可以指定-w选项为psql省略密码提示。

如果您打算拥有多个主机/数据库连接，则~/。Pgpass文件是可行的。

步骤:

Create the file using vim ~/.pgpass or similar. Input your information in the following format: hostname:port:database:username:password Do not add string quotes around your field values. You can also use * as a wildcard for your port/database fields. You must chmod 0600 ~/.pgpass in order for it to not be silently ignored by psql. Create an alias in your bash profile that runs your psql command for you. For example:alias postygresy='psql --host hostname database_name -U username' The values should match those that you inputted to the ~/.pgpass file. Source your bash profile with . ~/.bashrc or similar. Type your alias from the command line.

注意，如果设置了export PGPASSWORD= "变量，它将优先于文件。
