If I understood the original report correctly, they were complaining mostly about index size, so a table without indexes certainly isn't a real helpful comparison. Still, this brings up an important point: AFAICS the paper doesn't even mention which mysql storage engine they're using. So it's *really* hard to tell what we're comparing to. > Are all Postgresql indexes based on GIN & GiST? No, certainly not.
