Hi all! I'm new to Postgresql and I'm trying solve a problem: is there a way to know how many disk-pages are read
duringa query? Because I found out only how many disk-pages a relation has and I'd like to know if there is a system 
catalog or something else that stores this information

thanks,
Andrea Lazzarotto
