Aaron,
Would case studies work?
I suggest you mention the Netezza data warehousing
appliance - on their site they have comparisons against other systems which will
be impressive.
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 case:
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
:)
The problem is, this isn't a logical decision they are making. They are only comfortable with Micro$oft and when I mention a database they haven't heard of before, they cringe even though I have proven it's ability to serve all their needs for the last year.

What it comes down to is that I need to SELL them on the idea of using PostgreSQL or they may just take their business elsewhere just because I don't use Microsoft. I think they may actually rather pay tens of thousands of dollars more for that stamp from Borg Gates.
Are there good articles that compare the databases or talk about PostgreSQL - I need to site good references.
Thanks,
Aaron

Another thing you could ask them to prove why to use the other plataform.
There isn't many differencies about SGDBs performance for me. I prove it by myself and the results where better than Oracle in some cases.
I hope you could make, at least, them think about it.

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 convince them.
What are some good resources online that discuss PostgreSQL and how it compares to the "more popular" databases? While it really should be none of my customers' business what database I use (I am an application service provider), they still make a big deal out of it.
Thanks!
