Printable docs is a silly reason, but that link is to the docs for 8.2.4, so the
argument is not negated by the existence of that book. A dearth of books in
general is certainly a weak point for Postgres however.

Need some more reasons why Oracle over Postgres?:

1) Oracle has in-place upgrades. I know for a fact this has prevented some
large companies from going to Postgres.

2) Oracle RAC

3) Oracle sales people and a huge marketing department

4) Oracle runs on Windows. We do too, but did not for a long time and the
perception that we don't (or don't do it well) is still out there.

5) Training, certification, and the aforementioned books. We're very slowly
gaining traction in this area.

6) We've been tainted by our lumping together with MySQL, which makes
open-source databases in general look bad when people familiar with Oracle
examine MySQL and assume Postgres is similar in attitude, community,
features, and robustness.

I'm sure EDB could expand this list a bit as well. :)
