PostgresSQL vs. Informix

PostgreSQL Team,

I have a large OEM customer (one of the top 8 for Sun worldwide) that is
considering embedding PostgreSQL into the core of their primary product
instead of Informix.  He is trying to build his case for this change.
Do we have anything that I can forward to him (something like the
presentation you did at CEC?) to help him build his case?

This is an urgent request from my customer given that his timeline is
relatively short.  Any help you can give me will be very appreciated.

Thanks,

Chad Hendren

Original question:

Have you seen any studies (either by Sun or others) that compares
PostgresSQL to other commercial database software (Informix, Oracle,
Sybase,etc.)? I am interested seeing a feature by feature comparison of
PostgresSQL and Informix.
