In case anyone besides me is interested, installing these packages on CentOS4.2 seems to work. You can determine the correct mirror to use from: http://www.postgresql.org/ftp/binary/v8.0.4/linux/rpms/redhat/rhel- es-4/ The rpm command that I used was: rpm --upgrade --nodeps --hash -v <package url> Packages in order of installation: ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-libs-8.0.4-2PGDG.i686.rpm ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-contrib-8.0.4-2PGDG.i686.rpm ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-docs-8.0.4-2PGDG.i686.rpm ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-pl-8.0.4-2PGDG.i686.rpm ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-8.0.4-2PGDG.i686.rpm ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-server-8.0.4-2PGDG.i686.rpm ftp://ftp3.ca.postgresql.org/pub/binary/v8.0.4/linux/rpms/redhat/rhe l-es-4/postgresql-test-8.0.4-2PGDG.i686.rpm We are using 8.0.4 for development of a new application on a dedicated development server so stability and data conversion issues do not concern us for the moment. You are nonetheless advised not to install 8.0.4 over a 7.4.8 installation without first unloading all of the postgreSQL databases that you wish to preserve under 8.0.4.
