Hi Hari, What kind of warehousing are you thinking of? I would be very interested to discuss this topic since we made lots of experience in this field using Postgres. I think one of the biggest challenges in this field is not the use of RDBMS but the development AND maintenance of a proper data model. Without a decent model the database is nothing but a fancy file system (in extreme words).
