将 Inno Setup exec 函数中的命令传递到 pgsql 数据库中

Question

我正在运行宁以下代码试图从我的 Inno Setup 脚本读取的文件在我的 PostgreSQL 数据库中创建用户。不幸的是，唯一执行的命令是将我连接到数据库的 SET PGPPASSWORD 和 -U postgres elt 命令。我需要在数据库中运行的其他命令被忽略，我似乎无法找到将它们输入数据库的方法。我可以使用字符将命令输入到 PostgreSQL 数据库中吗？

ExecAsOriginalUser('cmd.exe', '/k ' +'"SET PGPASSWORD=postgres&"' + 
    InstallPath+ '\psql -U postgres elt -c '+ 'CREATE USER ' 
    + Users[UserCount - 1] + ' WITH PASSWORD ' + '''' 
    + Password + '''' + '& ' + '\g', '', SW_SHOW, ewWaitUntilIdle, ResultCode);

命令行输出：

psql: warning: extra command-line argument "-c" ignored
"": extra command-line argument "CREATE" ignored
"": warning: extra command-line argument "USER" ignored
"": extra command-line argument "postgres" ignored
"": extra command-line argument "WITH" ignored
"": extra command-line argument "PASSWORD" ignored
"": extra command-line argument "'postgres'\g" ignorepsql

您可能只需要将 SQL 括在双引号中：

ExecAsOriginalUser('cmd.exe',
    '/c SET PGPASSWORD=postgres& '
    + InstallPath + '\psql -U postgres elt -c "CREATE USER ' 
    + Users[UserCount - 1] + ' WITH PASSWORD ''' + Password + '''"',
    '', SW_SHOW, ewWaitUntilIdle, ResultCode);

首先在命令行中通过运行验证：

cmd.exe /c SET PGPASSWORD=postgres& C:\eltfiles\pgsql\bin\psql -U postgres elt -c "CREATE USER postgres WITH PASSWORD 'postgres'"
