Hi Peter, If you run into a scaling issue with PG (you will at those scales 1TB+), you can deploy Greenplum DB which is PG 8.2.5 compatible. A large internet company (look for press soon) is in production with a 150TB database on a system capable of doing 400TB and we have others in production at 60TB, 40TB, etc. We can provide references when needed - note that we had 20 successful customer references supporting Gartner's magic quadrant report on data warehouses which put Greenplum in the "upper visionary" area of the magic quadrant - which only happens if your customers can scale (see this: http://www.esj.com/business_intelligence/article.aspx?EditorialsID=8712) In other words, no matter what happens you'll be able to scale up with your Postgres strategy. - Luke On 11/26/07 10:44 AM, "Pablo Alcaraz" <pabloa@xxxxxxxxxxxxxxxxxxxx> wrote: > I had a client that tried to use Ms Sql Server to run a 500Gb+ database. > The database simply colapsed.
