Stumbled across this post by Joe Stagner of Microsoft:

It is basically a comparisson of ASP.NET vs PHP but it includes
comparissons of multiple RDBMS and operating systems.
Postgres comes out on top for most of the benchmarks against MySQL and
SQL Server, in fact in the authors original article he goes as far as
recommending using Postgres. More interestingly, the article seems to
indicate that W2K8 server is faster for postgres than Linux in many of
the scenarios.
Note that the linux version they were comparing was Ubuntu - which I
know from personal experience has very poor default settings for
shared_buffers due to Ubuntu's operating system defaults. Perhaps if
theses parameters were altered postgres would get a clean sweep.
Anyway - I know benchmarks of this type tend to be very limited in their
scope but good press all the same!
