postgreSQL use in production systems - Mailing list pgsql-general

We are currently performing a technology due dilligence on a software package
that uses postgreSQL as it's DBMS (on Unix).  Could you please provide me with
information on large-volume production systems build on this platform, as well
as, the suitablility of this platform for large volume applications.

Thank you very much.
