Improper SQL query in _img_assist_remove function

In drupal 6.2 with img_assist-6.x-1.0-beta1 and postgresql 8.1, I started to get an error when updating. (I didn't store the error, sorry :().

The error was when trying to run the following SQL query:
SELECT * FROM files f INNER JOIN image i WHERE f.fid = i.fid AND i.nid = 10 AND f.filename = '_original';

Which is constructed in _img_assist_remove function inside img_assist.module ($result = db_query("SELECT * FROM {files} f INNER JOIN {image} i WHERE f.fid = i.fid AND i.nid = %d AND f.filename = '%s'", $node->nid, $size['key']);).

The problem is that the SQL select is not properly coded. Should be:
* If you'd like an explicit inner join:
"SELECT * FROM {files} f INNER JOIN {image} i ON f.fid = i.fid AND i.nid = %d AND f.filename = '%s'"

* If you'd like to do it in an implicit way:
"SELECT * FROM {files} f, {image} i WHERE f.fid = i.fid AND i.nid = %d AND f.filename = '%s'"

The problem is that in current version (also in cvs) the query is wrong.

I cannot reproduce it since I did a rollback to drupal 5.7. But I think the bug is pretty isolated :)
