PostgreSQL
## Temporally install the old version emerge -1 dev-db/postgresql:9.3 ## Create database and config for the new version emerge --config dev-db/postgresql:9.5 ## Manually merge config d /etc/postgresql-9.{3,5}/pg_hba.conf #... ## Migrate cd /tmp sudo -u postgres -- pg_upgrade -d /var/lib/postgresql/9.3/data/ -D /var/lib/postgresql/9.5/data/ -b /usr/lib/postgresql-9.3/bin/ -B /usr/lib/postgresql-9.5/bin/ systemctl start postgresql-9.5.service sudo -u postgres /var/lib/postgresql/analyze_new_cluster.sh rm -R /etc/postgresql-9.3 /var/lib/postgresql/9.3
In some old instructions, steps can be found, which are not necessary anymore:
- Copy config files from
/etc/postgresql-*/
to/var/lib/postgresql/*/data/
(they are now symlinked) - Add
local all all trust
to/etc/postgresql-*/pg_hba.conf
(it it there by default)
