People often run much larger volumes than this on PostgreSQL, but
generally not without using connection pooling.

http://wiki.postgresql.org/wiki/Number_Of_Database_Connections

Personally, I managed a machine which typically had 3000 users
running queries against it while about 20 million
INSERT/UPDATE/DELETE statements per day were run against it.=20
Tuning showed best performance when we used connection pools with
35 connections for read-only queries and 6 connections for the DML.

Expect to spend some time adjusting the configuration for your
particular hardware and workload.
