Good morning, 

I am Rebecca Zahra and I am currently in my final year of Masters studies at the University of Malta. My thesis is about the usage of indexes for multi-dimensional data. 

I was going through the posts regarding GIST indexes and I came across the following http://dba.stackexchange.com/questions/39589/optimizing-queries-on-a-range-of-timestamps-two-columns

I was wondering if maybe you can help me with a question.  I know that an R-Tree index implementation is used on top of GIST to index spatial data. Can you please tell me what type of index is used on top of GIST to index range types? 

Thanks a lot for your time. Greatly appreciate
Rebecca
