Which Linux Distribution

We are about to launch a very large client/server environment and before we
lock down the production servers I thought I
would as if there is a particular linux distribution that keeps up or
postgresql is designed for more than another.  I know
that linux is linux but which linux (if any) is used for development
testing.

Also I haven't had many comments about my last post I have included it below
as well:

****************************************************************************

Subject: [ADMIN] Load of 4 Million Queries Read and or Write Per Second

That is 4 Million Queries per Second which is 14 Billion 400 Million per
hour.

This may sound a little big but this is what we will be launching on the 1st
December 2000 using postgresql and php.

It is a new generation client/server environment that allows
communication/transactions and information storage for b2b, b2c and p2p.

Does anyone have a qlue what will happen and what should I order now to
replace the box we have and what size
space should I clear in the office/warehouse for expansion.

I am serious and would like some feedback and input.

learning curve from commercial and mysql to postgresql.
