Reference to anybody working on this: the user code is 

Book.objects.filter(pubdate__startswith='2005')

and the generated query is

...
WHERE "SHARED_MODELS_BOOK"."PUBDATE" LIKE TRANSLATE(TO_TIMESTAMP(:arg0, 'YYYY-MM-DD HH24:MI:SS.FF') USING NCHAR_CS) ESCAPE TRANSLATE('\' USING NCHAR_CS)

That is, where the user code expects dates to be translated to strings, the backend tries to translate the string to a date in the middle of all the string translation operations.
