Subject: - All LIMIT queries must go through the pager or through
 db_query_range().   The syntax for db_query_range() was enhanced so it
 matches db_query(). So   you may pass extra arguments of the SQL statement
 which are checked via   check_query() and then substituted into the SQL
 statement. After these   optional arguments, you always pass $from and $count
 parameters which   define your range.  Most often, the $from is 0 and the
 count is the max   number of records you want returned.  Patch by Moshe.

- The pager_query() function for PEAR was enhanced so that it adds  proper
  GROUP BY statement counting the number of records to be paged. Patch by
  James Arthur.

- MSSQL database scheme by Moshe.
