Postgres "in the field"

REGARDING                Postgres "in the field"

We are contemplating using postgres in an internal project currently in
progress.  I have to give a presentation on rdbms that I've evaluated.  I'd
like to include a slide on what postgres is being used for "in the field".  

I'd like to get the warm fuzzy that postgres is not just being used for
post-graduate thesis work. 

So, what's everyone using postgres for?

TIA,
Andy
