UPGRADING FROM A PREVIOUS VERSION
---------------------------------
If upgrading from a non-compatible version (ie 8.0.x >> 8.1.x)
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
# su - postgres
# initdb -D /var/pgsql/data
# exit
# /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:
# useradd postgres
# passwd -l postgres
# mkdir -p /var/pgsql/data
# touch /var/log/postgresql
# chown postgres /var/pgsql/data /var/log/postgresql
# su - postgres
# initdb -D /var/pgsql/data
# exit
# /etc/rc.d/postgresql start
# su - postgres
# createdb test
# psql test
edit /etc/cron/weekly as root and add a line "/usr/sbin/rotatelog postgresql"
