I'd almost say it was the other way round. PostgreSQL is pretty easy to 
install - as root (paraphrasing what i actually just did):

yum install postgresql-server # will prompt to confirm
sudo -u postgres initdb
# possibly edit pg_hba.conf
service postgresql start
sudo -u postgres createuser -P -S developer # will prompt for a password
sudo -u postgres createdb -O developer development

pg_hba.conf is the file which defines access methods, and access control. 
With every package i have ever installed, it is created in a state which 
allows the normal console user to get access to the database. However, the 
details vary: IIRC, on OS X (with MacPorts), it is set up to use peer 
authentication for unix domain sockets (which is secure), and MD5 password 
authentication for TCP/IP sockets (which is fairly secure). However, a 
default install on Fedora 15 has no authentication on either kind of 
socket; that said, TCP/IP sockets are only opened on the loopback 
interface, so this is not that bad. An old installation on Fedora came 
with only unix domain sockets by default, and no TCP/IP. So, that file may 
need some tweaking.

So, not nearly as easy as installing Derby (which with a Sun JDK involves 
precisely zero steps), but not at all difficult. Suitable for a 
development machine.

Whereas i think the great strength of Derby is in production - if and only 
if you are distributing code to run on desktop machines. There, the less 
you need to install, the better, and the fact that Derby comes in the JDK 
makes it a bit of a slam-dunk. It's not a particularly great database, but 
you can't argue with the ease of installation.
