Examples of Large Datasets on Postgres?

Hi all,

I believe this relates primarily to advocacy, so am posting here. I would
like to find examples of organizations running large datasets on
PostgreSQL. The last survey on this (that I can find) is from 2004 (
http://www.postgresql.org/community/survey/26-how-large-is-your-postgresql-database/
).

I have also seen this example from 2008:
http://it.toolbox.com/blogs/oracle-guide/worlds-largest-database-runs-on-postgres-24979

Given these limited examples, I wonder if someone would be willing to
discuss their large PostgreSQL DB? I would like to write an article for my
blog.

The driving factor for me is that, in my local community college, where I
am taking database classes, the (admittedly biased) Oracle pros who are
teaching the classes keep referring to PostgreSQL as "light". Even when I
bring up the Yahoo example, they respond with, "I've never seen that".
While I can truly appreciate their bias (I am surely biased in quite the
opposite direction), I think they need to be willing to acknowledge that
their understanding of Postgres is limited.

I am here in Charlotte, North Carolina, home to the SouthEast LinuxFest and
a member of the Charlotte Linux User Group. I also did a presentation at
SELF on the Ltree extension module. In a prior life, I was the
Editor-in-Chief of LXer.com.

Again, I would love to write an article about Postgres running large
datasets (TB & PB range), if anyone would be willing to discuss such an
animal. I would like to focus on how you are using your Postgres and what
hardware you're running on, in somewhat similar fashion to the Yahoo
article.

Can anyone point me in the right direction? I realize I'm preaching among
evangelists on this list, but maybe some of the folks here know someone who
might be willing to talk?

Thanks,
Don
