syntax errors in postgres SELECT statements

Hi,

I have just installed the latest code snapshot on my Postgres-backed Drupal 6 site and get the following in my Postrgres logs:

2010-11-22 22:05:11 MSK FEHLER:  Syntaxfehler bei »A« bei Zeichen 299

	                    WHEN SUBSTR(n.title,1,1)='\''   THEN LOWER(SUBSTR(n.title,2))
	                    WHEN SUBSTR(n.title,1,2)='A '   THEN LOWER(SUBSTR(n.title,3))

	                    ELSE LOWER(n.title)
	                 END  FROM www_larsgrobe_de_6_node n left join www_XXX_6_biblio b  on n.vid=b.vid  inner join www_XXX_6_biblio_types bt  on b.biblio_type=bt.tid   WHERE n.type='biblio'   ORDER BY b.biblio_year desc, b.biblio_date desc,  CASE

	                    WHEN SUBSTR(n.title,1,1)='\''   THEN LOWER(SUBSTR(n.title,2))
	                    WHEN SUBSTR(n.title,1,2)='A '   THEN LOWER(SUBSTR(n.title,3))
	                    WHEN SUBSTR(n.title,1,3)='An '  THEN LOWER(SUBSTR(n.title,4))
	                    WHEN SUBSTR(n.title,1,4)='The ' THEN LOWER(SUBSTR(n.title,5))
	                    ELSE LOWER(n.title)
	                 END  asc  LIMIT 25 OFFSET 0

This seams to be related to the sort code, as I can display the bibliography when not sorted by date or type - sorting by author works fine.

Cheers, Lars.
