OpenACS 5.4.2 will run with PostgreSQL 7.3.2, 7.3.3, and 7.3.4 and 7.4.x. 7.4.7 is the recommended version of PostgreSQL.

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.
Special Notes for Debian.�
Debian stable user should install PostGreSQL from source + requires PostGreSQL 7.4.

Special Notes for Debian.

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
+        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
 ln -s /usr/include/postgresql/ /usr/include/pgsql
 ln -s /var/lib/postgres /usr/local/pgsql
 ln -s /usr/include/pgsql /usr/local/pgsql/include
-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 +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):

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.

Debian users should probably use adduser instead of - useradd. Type man adduser -

Set PostgreSQL to start on boot. First, we copy the postgresql.txt init script, which automates startup and shutdown, to the distribution-specific init.d directory. Then we verify that it works. Then we automate it by setting up a bunch of symlinks that ensure that, when the operating system changes runlevels, postgresql goes to the appropriate state. Red Hat and Debian and SuSE each work a little - differently. If you haven't untarred the OpenACS tarball, you will need to do so now to access the postgresql.txt file. -
