the resulting query ""SELECT django_date_trunc(""month"", ""blog_post"".""date_published"")  FROM ""blog_post"" LIMIT 1  GROUP BY 1 ORDER BY 1 ASC"" is wrong according to sqlite docs, LIMIT should go after GROUP BY (in fact - mostly in the end)."		closed	Database layer (models, ORM)	dev		fixed	qs-rf-fixed		Accepted	0	0	0	0	0	0
