Problem

1.6.9 fails against a PostgreSQL-based wiki. Example:

 <dpl>
  category=Teams
 </dpl>

...produces:

The DPL extension (version 1.6.9) produced a SQL statement which lead to a Database error.
The reason may be an internal error of DPL or an error which you made,
especially when using DPL options like titleregexp.
Query text is:
SELECT DISTINCT page.page_namespace as page_namespace,page.page_title as page_title, REPLACE(REPLACE(CONCAT(
IF(page.page_namespace=0, , CONCAT(CASE page.page_namespace WHEN 1 THEN 'Talk' WHEN 2 THEN 'User' WHEN 3 THEN 
'User_talk' WHEN 4 THEN 'SHARCNETWiki' WHEN 5 THEN 'SHARCNETWiki_talk' WHEN 6 THEN 'Image' WHEN 7 THEN 'Image_talk' 
WHEN 8 THEN 'MediaWiki' WHEN 9 THEN 'MediaWiki_talk' WHEN 10 THEN 'Template' WHEN 11 THEN 'Template_talk' WHEN 12 
THEN 'Help' WHEN 13 THEN 'Help_talk' WHEN 14 THEN 'Category' WHEN 15 THEN 'Category_talk' END, ':')), 
page.page_title), '_', ' '),'♣','⣣') as sortkey FROM page INNER JOIN categorylinks AS cl0 ON 
page.page_id=cl0.cl_from AND (cl0.cl_to='Teams') WHERE 1=1 AND page.page_is_redirect=0 ORDER BY sortkey ASC LIMIT 0, 
500

Error message is:
ERROR: LIMIT #,# syntax is not supported HINT: Use separate LIMIT and OFFSET clauses. 

This patch corrects the problem, and according to the MySQL manual should be fine there too. (I can't test that, though.)
