Re: TB-sized databases

I think either would work; both PostgreSQL and MS SQL Server have
success stories out there running VLDBs.  It really depends on what you
know and what you have.  If you have a lot of experience with Postgres
running on Linux, and not much with SQL Server on Windows, of course the
former would be a better choice for you.  You stand a much better chance
working with tools you know.
