pgsql fix

At line 115 you have

  db_query('INSERT into {files} (fid, nid, filename, filepath, filemime, filesize)  
             VALUES (%d, %d, "%s","%s","%s",%d)',
            $file['fid'], $node->nid, $file['filename'], $file['filepath'], $file['filemime'], $file['filesize']);

which unfortunately creates an error in postgresql because it expects single quotes around strings (as does mysql but it is a little more tollerant in this case, see http://mysql.com/doc/refman/5.0/en/string-syntax.html ).
I suggest changing the line to

  db_query("INSERT into {files} (fid, nid, filename, filepath, filemime, filesize)  
             VALUES (%d, %d, '%s','%s','%s',%d)",
            $file['fid'], $node->nid, $file['filename'], $file['filepath'], $file['filemime'], $file['filesize']);

as that code will work in both.

Thanks,
