今日、Ubuntu サーバー上のすべてのソフトウェアをアップグレードしました。
sudo aptitude upgrade
アップグレードがうまくいかず、postgresql が開始されず、次のエラーが発生しました。
alex@db:~$ sudo service postgresql start
* Starting PostgreSQL 9.5 database server[fail]
* The PostgreSQL server failed to start. Please check the log output:
2015-10-30 12:42:09 MSK FATAL: database files are incompatible with server
2015-10-30 12:42:09 MSK DETAIL: The database cluster was initialized with CATALOG_VERSION_NO 201507281, but the server was compiled with CATALOG_VERSION_NO 201510051.
2015-10-30 12:42:09 MSK HINT: It looks like you need to initdb.
アップグレード前にサーバー上にあった postgresql のバージョンは覚えていませんが、アップグレードの結果、1 つのデータ ディレクトリと 1 つのクラスターしか表示されませんでした。
alex@db:~$ ls /var/lib/postgresql/
9.5 Maildir
alex@db:~$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
9.5 main 5432 down postgres /var/lib/postgresql/9.5/main /var/log/postgresql/postgresql-9.5-main.log
というわけで、マイナーアップデートだったようです。
data dir をどこかにコピーして を実行したinitdb後、aptitude upgrade再び 9.4 クラスターが作成されていることに気付きました。
alex@db:~$ sudo cp /var/lib/postgresql/9.5/main /var/lib/postgresql/9.5/main.old
alex@db:~$ sudo /usr/lib/postgresql/9.5/bin/initdb -D /var/lib/postgresql/9.5/main/
alex@db:~$ sudo aptitude upgrade
alex@db:~$ ls /var/lib/postgresql/
9.4 9.5 Maildir
alex@db:~$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
9.4 main 5433 down postgres /var/lib/postgresql/9.4/main /var/log/postgresql/postgresql-9.4-main.log
9.5 main 5432 down postgres /var/lib/postgresql/9.5/main /var/log/postgresql/postgresql-9.5-main.log
今は問題なく動作していますが、保存したデータを /var/lib/postgresql/9.5/main.old から復元するにはどうすればよいですか? pg_upgrade が機能しません。そして...はい、アップグレードする前にバックアップを作成しませんでした。
