UPGRADING FROM A PREVIOUS VERSION
---------------------------------
If upgrading from a non-compatible version (ie 8.0.x >> 8.1.x or
8.x.y >> 9.a.b) be sure to dump the databases before upgrading and
restore them later.
Example: (for your convenience, there could be better ways to
achieve this)
# pg_dumpall -U postgres > pg.dump
# /etc/rc.d/postgresql stop
# mv /var/pgsql/data /var/pgsql/data-backup
# mkdir /var/pgsql/data
# chown postgres /var/pgsql/data
# sudo -u postgres initdb -D /var/pgsql/data
# /etc/rc.d/postgresql start
# psql -U postgres -f pg.dump postgres
Do not forget to update / copy old config files to /var/pgsql/data
NEW INSTALL
-----------
To complete the installation and create a test database you need to do
some additional steps or use the included post-install script.
# useradd -m -d /home/postgres -s /bin/false postgres
# passwd -l postgres
# mkdir -p /var/pgsql/data
# sudo -u postgres initdb -D /var/pgsql/data
# /etc/rc.d/postgresql start
# sudo -u postgres createdb test
# psql -U postgres test
Edit /etc/cron/weekly/syslog as root and add
a line "/usr/sbin/rotatelog postgresql"
