The analyst is making an argument like "Linux is weaker than Windows
because it has no graphical user interface in the kernel" - and
we're falling for it.

Would have been nice if they had pointed to the benchmark they
had in mind.   The only well known published benchmark I
see (on spec.org) that compares postgres to many of these other
databases made us look OK to me.

Postgres has this - in exactly the same way that Linux has a GUI.

And in the same way, Linux administration tools are nonexistant
in the kernel either.

Which makes it a good thing that postgres has pgadmin and webmin.

I'd bet it's on par with freetds / unixodbc and other tools to get
linux apps to work with sqlserver.

I totally agree we fall short here - for example most commercial
database vendors offer GIS data types.

Fortunately if we consider postgres as a platform, we have one
available from a third party.

For VLDB work, I agree F/OSS postgres doesn't really stand up, and
you need proprietary add-ons/forks.  However I note that many of the
larges databases in the world (Yahoo's Ebay's, etc) are indeed postgres
with extensions.

If the analysts report excludes any proprietary, I agree that
postgres as well as any other vendors who need proprietary
code should score low here.

OTOH, if the analyst's report permits proprietary code, it seems
postgres should score on top here.

I think the problem is that we're comparing an apples (just the core
postgres kernel) with oranges (the database kernels plus all the
supporting tools and apps from other vendors).

If you look at postgres as a broader platform, we do very well,
especially if you include non-BSD (both gpl and proprietary)
licensed extensions.
