> ########################################################
>
> Backup PGSQL config file(s)
> /home/pgsql/pg_hba.conf
> /home/pgsql/postgresql.conf
>
> Backup Bacula config file(s)
> /usr/local/etc/bacula-dir.conf
> /usr/local/etc/bacula-fd.conf
> /usr/local/etc/bacula-sd.conf
> /usr/local/etc/bconsole.conf
>
> Dump PGSQL Bacula DB
> /usr/local/bin/pg_dump bacula -v /home/bacula.sql
>
> Rename PG data directory
> mv /home/pgsql /home/pgsql.old
>
> Stop PGSQL & Bacula processes
> /usr/local/etc/rc.d/z-bacula.sh stop
> /usr/local/etc/rc.d/postgresql stop
>
> Uninstall Bacula Server & Client and any other Bacula package
> cd /usr/ports/sysutils/bacula-server && make deinstall clean
> cd /usr/ports/sysutils/bacula-client && make deinstall clean
>
> Uninstall Postgresql 8.3 Server & Client
> cd /usr/ports/databases/postgresql83-server && make deinstall clean
> cd /usr/ports/databases/postgresql83-client && make deinstall clean
>
> Install Postgresql 9.2
> Install /usr/ports/databases/postgresql92-server
> Install /usr/ports/databases/postgresql92-client
>
> Initialize PGSQL db
> initdb -D /usr/local/pgsql/data
> if this gives you an error message
> stop pgsql then 'rm -rf /home/pgsql/data'
> start pgsql
> then 'initdb -D /home/pgsql/data' - should work this time
>
> Install Bacula
> cd /usr/ports/sysutils/bacula-server && make install clean
> cd /usr/ports/sysutils/bacula-client && make install clean
>
> Restore PGSQL config files
> /home/pgsql/pg_hba.conf
> /home/pgsql/postgresql.conf
>
> Restore Bacula config files
> /usr/local/etc/bacula-dir.conf
> /usr/local/etc/bacula-fd.conf
> /usr/local/etc/bacula-sd.conf
> /usr/local/etc/bconsole.conf

> Configure Bacula as follows:
> make pgsql member of bacula group
> su pgsql
> /usr/local/share/bacula/create_bacula_database
> /usr/local/share/bacula/make_bacula_tables
> /usr/local/share/bacula/grant_bacula_privileges
> psql bacula < bacula.sql
> If cannot retrieve bacula.sql file for some reason, can
> restore from the most recent tape as follows:
> bextract <exact volume name of catalog> ('man bextract' for
> more details)
> start pgsql
> start bacula
> remove pgsql as member of bacula group
>
> Test
> start bconsole and verify status of director
> start a simple backup job and verify

> Questions:
>
> 1) Do I actually need to remove the bacula packages?
>
> 2) Are there any special steps that I'm missing when configuring the
> bacula databases? Do I need to run 'update-bacula-tables' somewhere in
> there?
>
> 3) Is PGSQL 9.2 considered stable? 9.1 had some serious bugs but these
> appeared to have been squashed.
>
> 4) Are there any special parameters I need to consider when going from
> PGSQL 8.3 to 9.2 especially in the postgresql.conf?
>
> 5) Any other caveats?
>
> 6) pg_upgrade: I came across this new function. Apparently you can upgrade
> databases from 8.3.x to 9.2.x with some caveats as described in the "
> Limitations in Upgrading from PostgreSQL 8.3" section of this link
> http://www.postgresql.org/docs/9.2/static/pgupgrade.html. If you've used
> this, would you care to share your experiences?
