PostgreSQL DB size and other questions

[OregonPostgreSQL]

Working with startup that will have data ranging from 4TB to 100TB
at each co-location. Could, at some time, exceed 100TB over 3-5 years.

Financial application.

Attempting to find large PostgreSQL DB users that can tell me
where my limits are and concerns to be aware of.

Will be 1-3M users. Maybe up to 5-10% online at any given time.

Global product in nature with co-locations that can be located
in US, Canada, UK, EU, Australia, and Japan. More may be added
dependent on acceptance

Replication asych required.

Snapshot backups.

DB cleaning, re-indexing a concern.

DB stability and response

Using new Sun Galaxy (AMD) blade servers and E2900 for possible application
DB server.

Would like to use blade servers to scale, but not sure what PostgreSQL will handle.

Any feedback appreciated.
