Install file doesn't respect database table prefixes

Subform module does not install correctly, when your drupal installation is configured to use database table prefixes.

In settings.php of your drupal installation you can define a prefix, that is used for all drupal tables. db_query() takes care of the prefix automatically, but you have to put every table name in curly braces: {table_name}. (See http://drupal.org/node/22795 for more info).

So please update "subform.install" file and put every table name in curly braces like:

CREATE TABLE IF NOT EXISTS {node_relation_instances} (
                `node_one` int(10) NOT NULL default '0',
                `node_two` int(10) NOT NULL default '0',
                `type` int(10) unsigned NOT NULL default '0',
                `id` int(10) unsigned NOT NULL auto_increment,
                PRIMARY KEY  (`id`),
                KEY `node_one` (`node_one`,`node_two`,`type`)
              ) ENGINE=MyISAM DEFAULT CHARSET=latin1;
