The way it works with Postgres is that discrete transactions/queries
only run on a single processor. So if you only have 1 user running 1
session, Postgres will never use more than 1 CPU.

With multiple users and/or multiple sessions, work is spread over the
multiple CPUs.

I'm sure Postgres could handle it. Whether the hardware you currently
have spec'd out could handle it or your application framework could
handle it is a totally different story. We could give you our best guess
based on more detailed info -- like how big is the total & working
dataset, what are the usage patterns, what kind of queries/transactions
are most common, etc. -- but you will definitely have to do your own
profiling to get accurate numbers.
