セルフホスティングユーザー向けPostgreSQL 18アップデート

:warning: 警告! アップグレードには大量の空きディスク容量(データベースサイズの2倍)が必要です。

DockerイメージをPostgreSQL 18にアップグレードするための変更を適用しました。コマンドラインからDiscourseを再構築するサイト管理者は、以前のPostgreSQL 15からPostgreSQL 18にアップグレードされます。2025年にPostgreSQL 15のアップデートが行われた際にアップグレードを見送った場合、そのアップグレードをスキップして直接PostgreSQL 18に進むことができます。

以前にアップグレードを見送った場合は、app.yml内のPostgreSQLテンプレートを templates/postgres.13.template.yml から templates/postgres.template.yml に変更してください。

どのアップグレードでも同様ですが、作業を行う前にバックアップを取得することを強く推奨します。

ロケールの変更

過去には、OSのアップグレード時などにglibcが更新された際にインデックス破損が発生することがありました。PostgreSQL 17以降、OSのglibcと独立した組み込みロケールプロバイダが導入され、バージョン間で安定性が保たれるようになりました。今回のアップグレードに伴い、C.UTF-8ロケールを使用するこの組み込みプロバイダに移行します。このロケールはコードポイント順に基づいており、前述の安定性の理由から推奨されます。

ロケールの変更を実現するためには、まず組み込みロケールプロバイダを使用して新しいDBクラスターを作成し、その後DBをダンプしてこのクラスターにリストアする必要があります。このため、インプレースアップグレードを実行していた以前のアップグレードよりもディスク容量の要件が大きくなります。

アップデート

公式インストールガイド(シングルコンテナ)

次回再構築時、最後に以下のメッセージが表示されます。

-------------------------------------------------------------------------------------
POSTGRESのアップグレードが完了しました

旧15のデータベースは /shared/postgres_data_old に保存されています

アップグレードを完了するには、以下を使用して再度再構築してください:

./launcher rebuild app
-------------------------------------------------------------------------------------

これはアップグレードが正常に完了したことを意味します! サイトを復旧して稼働させるには、再度再構築を実行するだけです。

データコンテナインストール

discourse_dockerリポジトリに提供されているサンプルに基づいた専用データコンテナを使用しているセットアップを実行している場合は、PostgreSQLを安全かつクリーンにシャットダウンすることを確認する必要があります。

現在では、数分にわたるクエリを実行するバックグラウンドジョブが動作しているため、Webコンテナをシャットダウンすることでデータコンテナの安全なシャットダウンを支援できます。

./launcher stop web_only
./launcher stop data
./launcher rebuild data
./launcher rebuild data
./launcher rebuild web_only

データコンテナに対して最初の再構築を実行する前に、PostgreSQLのログをtailして正常にシャットダウンされたか確認できます。

tail -f shared/standalone/log/var-log/postgres/current を実行すると、クリーンな場合、以下のログが表示されます。

2025-01-24 09:19:06.437 UTC [37] LOG:  received smart shutdown request
2025-01-24 09:19:06.444 UTC [37] LOG:  background worker "logical replication launcher" (PID 54) exited with exit code 1
2025-01-24 09:19:06.446 UTC [49] LOG:  shutting down
2025-01-24 09:19:06.468 UTC [37] LOG:  database system is shut down

アップデートの延期

次回再構築時にアップデートを延期する必要がある場合は、app.ymlファイルのPostgreSQLテンプレートを "templates/postgres.template.yml" から "templates/postgres.15.template.yml" に変更することで切り替えることができます。

ただし、アップグレード後にこの変更を元に戻すことを忘れるサイト管理者もいるため、推奨されません。

アップデート後のオプションタスク

PostgreSQL統計の最適化

アップデート後、新しいPostgreSQLにはテーブル統計が準備されていません。以下のコマンドを使用して生成できます。

docker exec -u postgres app \
	/usr/lib/postgresql/18/bin/vacuumdb -d discourse --analyze-in-stages

旧データのクリーンアップ

標準インストールの場合、以下のコマンドでPG15形式の旧データを削除できます。

cd /var/discourse
./launcher cleanup

別のデータコンテナを使用している場合は、以下のようにバックアップコピーを削除する必要があります。

rm -fr /var/discourse/shared/data/postgres_data_old/

FAQ

ソースクラスターがクリーンにシャットダウンされませんでした

上記のメッセージと共にアップグレードが失敗した場合、より単純なアプローチを試して状態を改善できます。

./launcher start app で旧コンテナを再起動します。稼働するまで数分待ちます。

次に ./launcher stop app で再度シャットダウンします。その後、ログをtailしてクリーンなシャットダウンだったか確認します。

tail -f shared/standalone/log/var-log/postgres/current
2025-01-24 09:19:06.437 UTC [37] LOG:  received smart shutdown request
2025-01-24 09:19:06.444 UTC [37] LOG:  background worker "logical replication launcher" (PID 54) exited with exit code 1
2025-01-24 09:19:06.446 UTC [49] LOG:  shutting down
2025-01-24 09:19:06.468 UTC [37] LOG:  database system is shut down

ログにデータベースがシャットダウンされたことが示されていない場合は、旧コンテナを再度起動し、./launcher enter app で進入し、以下のコマンドを実行して、完了後にもう一度ログをtailします。

export SVWAIT=300
sv stop nginx
sv stop unicorn
sv stop postgres
exit

ログが上記のようになった場合、./launcher rebuild app を使用して再度アップグレードを試すことができます。

データベース「postgres」の lc_collate 値が一致しません

このエラーは、データベースでデフォルト以外のロケールを使用している場合に発生します。成功させるには3つの変数が必要であると報告されています。app.ymlファイルの env: セクションに以下の3行が含まれていることを確認してください。

  LC_ALL: en_US.UTF-8
  LANG: en_US.UTF-8
  LANGUAGE: en_US.UTF-8

en_US.UTF-8 をあなたのロケールに変更してください。

再構築のたびにアップグレードが繰り返される(アップグレードループ)

この現象が発生した場合、アップグレードログには以下内容が含まれます。

mv: cannot move '/shared/postgres_data' to '/shared/postgres_data_old/postgres_data': Directory not empty
mv: cannot move '/shared/postgres_data_new' to '/shared/postgres_data/postgres_data_new': Directory not empty

これは、最後のアップグレードからのファイルがまだ残っていることを意味します。続行する前にそれらを他の場所へ移動してください。

PostgreSQL 15のアップデートをスキップしました。今どうすればよいですか?

このガイドの上部にある標準的な手順に従うことができます。これにより、問題なく現在のバージョンから18にアップグレードされます。

フリーディスクスペースが不足している場合、どのような(望ましくは)優雅な失敗が発生するでしょうか? そのパスを実行する人が必ず現れます!

フリーディスクスペースが不足している方の場合、バックアップを取得し、クリーンインストールにリストアすることで、移行として機能するでしょうか?

(その場合、オペレーティングシステムの新しいLTSバージョンへのアップグレードも良い機会かもしれません。Ubuntu 26.04はかなり新しいバージョンで、26.04.1はまもなくリリースされる予定です。インプレースでのアップグレード試行よりも、OSのクリーンインストールの方がトラブルが少ないかもしれません。)

この投稿のメール通知を受け取っていなければ、私もそうしていました :raised_back_of_hand: :flushed_face:

確認ですが、これはすでに適用されていますか?

もし今朝遅くまでコマンドラインからアップデートを実行した場合、すべてが適用されますか?

アップグレードスクリプトは空き容量をチェックし、安全である場合にのみ処理を進めます。

ディスク容量が critically( critically 重要)になる可能性のあるプロセスには2つのステップがあります。もし空き容量チェックをバイパスした場合、ここでトラブルに直面する可能性があります:

  1. pg_dump を実行して旧データベースからデータを抽出するとき(この時点で DB ストレージの2倍が必要)。
  2. pg_restore を実行してデータを新データベースに挿入するとき(この時点で DB ストレージの3倍が必要)。

この状態から回復するには、/shared/postgres_dump/shared/postgres_data_new を削除する必要があります。

なお、アップグレード終了時に一時的な pg_dump ファイルは削除されますが、万が一に備えてアップグレード前の DB データは /shared/postgres_data_old に保持されます。すべてが正常に動作していることを確認できたら、ディスク容量を確保するためにそのディレクトリを削除することになるでしょう。

PG15 サイトで Discourse のバックアップを取得し、PG18 サイトにリストアするテストを行いました。私の環境では機能しましたが、これは公式にサポートされている方法ではありません。まず本番環境ではない環境で十分にテストし、ロールバックの手段が確保されていることを確認してください!

アップグレードスクリプトで使用されるプロセスを研究することをお勧めします。特別なストレージ要件がある場合、それをあなたのニーズに合わせて調整できるはずです。繰り返しますが、まずはテストしてください:

はい、これはすでに discourse_docker に実装されていますmain ブランチを pull するか、./launcher rebuild app を実行すれば適用されます。

アップグレードを延期したい場合は、discourse_docker を main ブランチから切り離すことで 偶発的なアップグレードを防ぐことができます。

「非常に大きい」というのは具体的にどのような意味でしょうか?

データベースの予備容量が現在のサイズの3倍必要、と解釈しましたが、サイズは関係ありませんか?

「いいね!」 1

申し訳ありません。その警告メッセージは表現が悪く、かつ誤りでした。

ディスク上の既存のデータベースに加えて、ダンプ出力と復元中の新しいデータベースのコピーに必要な十分な空き容量が必要です。pg_dumpの出力は通常、データベースのデータディレクトリよりも小さいため、現在のデータベースサイズの2倍の空き容量があれば十分です。アップグレードスクリプトでこれを修正します。

追記:空き容量のチェックは、3倍から2倍のデータベースサイズを確認するように更新されました。

シングルコアのVMでは、以下の制限により、PG15の postgres.15.template.yml を使用し続ける必要があるようです:

pg_dump: error: -j/--jobs must be in range 1..2147483647

または、1つのCPUを使用するために web.template.yml-j1 にパッチ適用します。(次回ビルド時にデフォルト値に戻ります)。

はい、そのような構成も存在します!:blob_wave:

nproc の計算方法により、このエラーが発生しました(シングル vCPU で実行しています):-j/–jobs は 1..2147483647 の範囲内である必要があります($(($(nproc) - 1)) = 1 - 1 = 0 となるため、-j0 を指定しようとしています)

アップデートスクリプトは、-j$(( $(nproc) > 1 ? $(nproc) - 1 : 1 )) のような形式に更新されるべきでしょう。

あるサーバーで以下の問題が発生しました:

私は以下のディレクトリを移動することでこの問題に対処しました:

cd /var/discourse/shared/standalone
mv postgres_data_older postgres_data_oldest
mv postgres_data_old postgres_data_older

その後、./launcher rebuild app を実行すると以下のように完了しました:

-------------------------------------------------------------------------------------

To complete the upgrade, rebuild again using:

./launcher rebuild app

おそらく pg15 から pg18 へのアップグレードが原因でしょう。

私も同じ問題に遭遇したようです。

/var/discourse/templates/web.template.yml で変更が必要な行は、bundle install のジョブ数に関する行です(209行目付近):

変更前(1 CPU のホストで失敗):

- su discourse -c 'bundle install --jobs $(($(nproc) - 1)) --retry 3'

変更後:

- su discourse -c 'bundle install --jobs 1 --retry 3'

-j1 ではなく --jobs 1 です。Bundler は --jobs を使用します。-jtemplates/postgres.template.yml(および postgres.18.template.yml)内の pg_dump / pg_restore 用です。例えば、Postgres のアップグレード失敗が再び発生した場合は、-j$(($(nproc) - 1))-j1 に変更してください。

私は以下の方法で解決しました。

d/shutdown_dev

# ローカルデータベースを削除
sudo rm -rf ~/discourse/data/postgres

# データベースを再初期化
d/boot_dev -i

ローカル開発データが失われます!!!テスト環境から復元することを検討してください。

コア数に関する修正が準備中です。シングルCPUユーザーがこんなに多いことに気づいていませんでした。申し訳ありません!

コア数の検出を nproc --ignore=1 を使用するように更新しました。

最初のアップグレードは正常に完了しましたが、途中で奇妙な中間コンテナ接続エラーが発生し、データを再度再構築することで解決しました。

(これは2つのコンテナで構成されています)。

しかし、最終的にはすべて順調に終わりました。

この作業への多大なご努力に心より感謝申し上げます!
