Backup a Postgresql database in script using ado.net

Sql Server has the capability to backup a database to a file using ado.net

var path = @"C:\MyPath";
var databaseName = "Foo";

var backupFilename = string.Format ( "{0}.BAK", databaseName );
var backupPath = Path.Combine ( path, backupFilename );

if ( File.Exists ( backupPath ) )
  File.Delete ( backupPath );
                    
using ( var cmd = DbConnection.CreateCommand () )
{
   var selectQuery = 
      string.Format ( "BACKUP DATABASE {0} TO DISK = '{1}'", 
                       databaseName, backupPath );

   cmd.CommandType = CommandType.Text;
   cmd.CommandText = selectQuery;

   cmd.ExecuteNonQuery ();
}                    

I have seen pg_dump, and understand it is an exe installed by Postgre to backup a database. I would not have access to the server to run pg_dump. Can Postgre pg_dump be run from ado.net or is there a script alternative to it that could be used.
