There should be one master folder named something like
postgresql-7.4.2
cd into that directory, and read the INSTALL file. Basically, you'll need
to do:
./configure
make
make install
to install postgresql, then you'll need to run initdb as the postgres
super user and start the database. It's not that hard, really, just take
your time.

Access is a single user database system designed for simple databases.
MySQL is a very simple database server designed for speed with one or two
users.
Postgresql is a full featured relational database server in the same class
as Oracle or db2 in terms of performance, scaling, and features.

MySQL is easier to learn, but it teaches you bad habits. Access is pretty
easy, but also has some quirks. Postgresql is likely the hardest to
learn, but the most rewarding once you know it. It is likely to be able
to "take you further" than the other two.

Just easier for a beginner. The basic concepts of database don't get
easier to understand with any of the products, because the understanding
is the hard part, not the UI of the database.

Learn Postgresql, it will take you farther (Oracle, db2, etc... will come
easier to you if you learn postgresql.)
