I actually didn't know about materialized views but from what I've read it seems like this wouldn't be a good place to put it to work just because the conditions on the calendar where changed pretty frequently (most of them weren't, like I said on my previous post, but some were and from that I read that could be a problem since the view needed to be updated frequently). It feels really good to learn something new, I'm thinking of some scenarios which might improve with this type of views, thanks!
