I am left with a broken postgresql since my upgrade to Fedora 24. Starting the service retruns this error: # /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 ------------------------------------------ ------------------------------------ # cat /var/lib/pgsql/upgrade_postgresql.log -- connection to database failed: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/home/postgres/.s.PGSQL.5432"? could not connect to old postmaster started with the command: "/usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/db/pgsql/data-old" -o "-p 5432 -b -c listen_addresses='' -c unix_socket_permissions=0700 -c unix_socket_directories='/home/postgres'" start Failure, exiting --------------------------------------------- What am I supposed to do now? It seems a trick would be to install last version 9.4.8 alongside, then run both 9.4.8 and 9.5 with my data for 9.4 and new empty data base for 9.5, then dump from older to new one db. Is it correct? Anyway to make postgresql-setup works ?
