Would case studies work?
I suggest you mention the Netezza data warehousing appliance - on their

Although annecdotal, in my case I had an application running on SQL
Server. It could not keep up with the data throughput due to the nature
of the application.
It was running on state of the art hardware, ubt it just could not
handle such a high OLTP load.
Moved to PostgreSQL, I am running 4x the transaction level as before,
and the database does not even feel it.
Additionally, the richness of data structures and features of PostgreSQL
allowed us to vastly improve the speed at which the presentation layer
can render the data.
The following link has some good PDF's which might help you make your
Granted, you are not selling them a Netezza appliance, but the Netezza
appliance is based on PostgreSQL. If it is good enough for those types
of solutions, it probably is so for yours as well :)

Assunto: [pgadmin-support] Motivations for PostgreSQL
I have a customer who is beginning to give more
attention to the applications we host for them. They recently asked
what database we use and I told them PostgreSQL. They had never heard
of it and really like Micro$oft SQL Server. I explained to them the
added cost and how PostgreSQL is a solid database but I need more to
What are some good resources online that discuss
PostgreSQL and how it compares to the "more popular" databases? While
