My upgrade from Fedora 23 to 24 left me with a broken postgresql. # /usr/libexec/postgresql-ctl start -D /db/pgsql/data -s -w -t 270 FATAL: 22023: database files are incompatible with server DETAIL: The data directory was initialized by PostgreSQL version 9.4, which is not compatible with this version 9.5.3. LOCATION: ValidatePgVersion, miscinit.c:1364 pg_ctl: could not start server Examine the log output. <Note: my data are in /db/pgsql/data> --------------------------------------------- # postgresql-setup --upgrade * Upgrading database. ERROR: pg_upgrade tool failed ERROR: Upgrade failed. * See /var/lib/pgsql/upgrade_postgresql.log for detai ------------------------------------------ It seems I must install 9.4.8 alongside my current 9.5.3, then dump a backup from 9.4.8 and restore with 9.5.3. Is it possible to install 9.4.8 ? I found 9.4.8 .rpm packages for Fedora 23. How can I install them without touching anything to 9.5? Is there any other solution to solve this initialisation issue?
