Special notes for Mac OS X.�If you are running Mac OS X prior to 10.3, you should be able to install and use PostGreSQL 7.3.x. Mac OS X 10.3 requires PostGreSQL 7.4.
Debian stable user should install PostGreSQL from source as detailed below, or they should use the www.backports.org backport for Postgres to get a more current version. Debian unstable users: the following process has been known to work (but you should double-check that the version of PostGreSQL is 7.3 or above):
For Debian stable users, you can use backports, by adding this line to the /etc/apt/sources.list
- deb http://www.backports.org/debian stable bison postgresql openssl openssh tcl8.4 courier debconf spamassassin tla diff patch neon chkrootkit
-
- apt-get install postgresql postgresql-dev postgresql-doc

and proceed to Tune postgres. (OPTIONAL) or to the +su postgres -c "/usr/lib/postgresql/bin/createlang plpgsql template1"
and proceed to Tune postgres. (OPTIONAL) or to the next section.
Special Notes for Red Hat.�Red Hat users: If you install PostgreSQL 7.3.2 from the Red Hat 9 RPM, you can skip a few steps. These shell commands add some links for compatibility with the directories from a source-based install; start the service; create a new group for web service users, and modify the postgres user's environment (more - information):

Something similar may work for other binary packages as well.
Safe approach: install from source
Unpack PostgreSQL 7.4.7.�If you have not downloaded the postgresql tarball to
- /var/tmp/postgresql-7.4.7.tar.gz,
- get it.

ALTERNATIVE: Unpack PostgreSQL 7.4.7.�If you have not downloaded the postgresql tarball to
- /var/tmp/postgresql-7.4.7.tar.bz2,
- get it.

Install Bison.�Only do this if bison --version is smaller than 1.875 and you install PostgreSQL 7.4 from cvs instead of tarball.

Create the Postgres user.� Create a user and group (if you haven't done so before) for PostgreSQL. This is the account that PostgreSQL will run as since it will not run as root. Since nobody will log in directly as that user, we'll leave the password blank.

- useradd. Type man adduser
