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

8年后……

在我的mac上，我必须在文件中添加一行 ~ /。pgpass:

<IP>:<PORT>:<dbname>:<user>:<password>

还看到: https://www.postgresql.org/docs/current/libpq-pgpass.html https://wiki.postgresql.org/wiki/Pgpass

只需使用PGPASSWORD即可完成。我使用的是psql 9.5.10。对你来说，解决办法是

PGPASSWORD= psql -U myuser密码< myscript.sql密码

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。

你必须创建一个密码文件:更多信息请参见http://www.postgresql.org/docs/9.0/interactive/libpq-pgpass.html。
