PostgreSQL enterprise references

Greetings,

I need to provide data for a compuer illiterate CFO to
stand an argument with Oracle zealots on whether new
ERP system should be based on Oracle or PostgreSQL.
CFO  looks extremely favorably towards PostgreSQL but
asks for some real-life examples of using PostgreSQL in
finantial applications. Shannon Medical Center,
Mohawk Software, Vanten Inc. and BASF case studies
provided on Advocacy web page do not quite qualify.
Are there some other examples?

Thnaks in advance,
Nicolai Tufar
