comment Best program or tool for visualising big data sets really fast 10-20 GB data if the users don't know squat about GIS?
I think this question needs to be much more specific to result in useful answers. 10-20 GB of mostly vector data is very vague. Are they points? Polygons? Do you want users to be able to choose cartographic styles? Zoom levels? See individual features? GPU considerations don't really seem relevant this early on.

comment Simplifying geometries and calculating non-spatial averages
'zooming' suggests that you are viewing the data via a viewer of some sort; it's not an inherent property that you can calculate. If you have some spatial unit that you can aggregate upwards, perhaps you could use that? Can you post an example of the data illustrating the table structure?

comment Computing intersections for each geometry in a table
Out of curiosity, is a.id < b.id better than a.id != b.id as you will reduce the total number of queries?

This is a four year old comment that's obsolete. While short, I don't think it needs to be expanded.
