Perhaps you should clarify here - what exactly do you mean by millions of "database enquiries per minutes"?

Will these be reads? Or will there be lots of updating going on?

What is the nature of these database "enquiries"?

Fine - Oracle won't be supported on *BSD.

Yes - but what sort of heavy duty use? MySQL will be better IMHO for reading - less transactional overhead - which is both good and bad!

All of the commercial vendors specifically forbid benchmarks - except the
ones they choose to publish themselves!

32GB of RAM is a large system - but RAM isn't everything! What is the OS going to be? That's your first decision.

What about the disk configuration? What's the CPU configuration?

Generally a web server feeds user input to an app server which then fires SQL at a database.

These tiers should all run on separate machines - or at least separate virtual machines.

You could look at Firebird - it's solid and simple to administer. The answer to this
question depends on your requirements, which you haven't explained enough here.
