The 2MASS sky survey point-source catalog http://www.ipac.caltech.edu/2mass/releases/allsky/doc/sec2_2a.html is 470 million rows by 60 columns; I don't have it loaded up but a very conservative estimate would be a quarter terabyte. (I've got a copy of the data ... 5 double-sided DVDs, gzipped ...) I haven't heard from Rae Stiening recently but I know he's been using Postgres to whack that data around since about 2001 (PG 7.1 or so, which is positively medieval compared to current releases). So at least for static data, it's certainly possible to get useful results. What are your processing requirements? regards, tom lane
