 I'm sorry, I can't help you, but I thought just to mention that because 
 you order your results by postDate in latter query, the whole query must 
 be fetched and therefore taking 50 of them doesn't speed up it at all. 
 Creating indexes would probably help if there aren't any, but I have no 
 idea how sqlite supports them.
