Red Hat Enterprise Linux 8 に PostgreSQL 15 のクライアントをインストールしてみた
Application Streamsを使いこなそう
Red Hat Enterprise Linux 8にPostgreSQL 15のクライアントをインストールしたいな
こんにちは、のんピ(@non____97)です。
皆さんはRed Hat Enterprise Linux 8(以降RHEL 8)にPostgreSQL 15のクライアントをインストールしたいなと思ったことはありますか? 私はあります。
2023/4にAmazon Aurora PostgreSQL 15がGAされました。
これにより、PostgreSQL 15のクライアントの需要がより増えると予想します。
しかし、RHEL 8でデフォルトでインストール可能なPostgreSQLのクライアントのバージョンは10です。
せっかくRHELを使っているのに標準リポジトリ外からインストールするのも、なんだか勿体無い気がします。
ですが、安心してください。PostgreSQL 15のクライアントをRHEL 8にインストールすることは可能です。
以降、その方法を紹介します。

検証環境
検証環境は以下の通りです。
EC2インスタンスはRHEL 8.8です。
$ cat /etc/redhat-release Red Hat Enterprise Linux release 8.8 (Ootpa) $ rpm -qi kernel Name : kernel Version : 4.18.0 Release : 477.10.1.el8_8 Architecture: x86_64 Install Date: Wed 03 May 2023 03:42:27 PM UTC Group : System Environment/Kernel Size : 0 License : GPLv2 and Redistributable, no modification permitted Signature : RSA/SHA256, Mon 10 Apr 2023 01:53:24 PM UTC, Key ID 199e2f91fd431d51 Source RPM : kernel-4.18.0-477.10.1.el8_8.src.rpm Build Date : Wed 05 Apr 2023 06:05:30 PM UTC Build Host : x86-vm-07.build.eng.bos.redhat.com Relocations : (not relocatable) Packager : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla> Vendor : Red Hat, Inc. URL : http://www.kernel.org/ Summary : The Linux kernel, based on version 4.18.0, heavily modified with backports Description : This is the package which provides the Linux kernel for Red Hat Enterprise Linux. It is based on upstream Linux at version 4.18.0 and maintains kABI compatibility of a set of approved symbols, however it is heavily modified with backports and fixes pulled from newer upstream Linux kernel releases. This means this is not a 4.18.0 kernel anymore: it includes several components which come from newer upstream linux versions, while maintaining a well tested and stable core. Some of the components/backports that may be pulled in are: changes like updates to the core kernel (eg.: scheduler, cgroups, memory management, security fixes and features), updates to block layer, supported filesystems, major driver updates for supported hardware in Red Hat Enterprise Linux, enhancements for enterprise customers, etc.
こちらの環境はAWS CDKでデプロイしました。

インストール後、クライアントのバージョンを確認します。
$ psql --version psql (PostgreSQL) 10.23
確かにバージョン10.23のクライアントですね。
それでは、10.23のクライアントを使ってAurora PostgreSQL 15.2に接続します。

Type "help" for help.
「クライアントpsqlとサーバーのメジャーバージョンが違うため、psqlの機能が動作しないかもしれない」と警告されました。これはあまり気分が良いものではありません。
また、pg_dumpに至っては「バージョンが異なるため中止する」となってしまいました。
$ pg_dump pg_dump: server version: 15.2; pg_dump version: 10.23 pg_dump: aborting because of server version mismatch
これはクライアントとサーバーのバージョンを合わせたくなりますね。
PostgreSQL 15のクライアントのインストール
Application Streamsの確認
次にPostgreSQL 15のクライアントを指定してインストールします。
これは「Application StreamsでPostgreSQL 15のストリームを指定する」ことで行えます。
Application StreamsとはコアとなるOSパッケージと異なるライフサイクルで提供するパッケージ管理形式です。
以下記事でもApplication Streamsでストリームを指定してPythonをインストールしています。
Application Streamsを使う場合は、ライフサイクルに注意する必要があります。Application Streamsにおけるライフサイクルの考え方はRed HatのSAの方のスライドが参考になります。
RHEL 8におけるPostgreSQL 15の廃止日は2028/5です。なお、RHEL 8のEOLは2029/5です。

PostgreSQL 15のストリームの有効化
次にPostgreSQL 15のストリームの有効化を行います。
$ sudo dnf module enable postgresql:15 Updating Subscription Management repositories. Unable to read consumer identity This system is not registered with an entitlement server. You can use subscription-manager to register. Last metadata expiration check: 0:05:18 ago on Tue 30 May 2023 06:25:59 AM UTC. Dependencies resolved. The operation would result in switching of module 'postgresql' stream '10' to stream '15' Error: It is not possible to switch enabled streams of a module unless explicitly enabled via configuration optionmodule_stream_switch. It is recommended to rather remove all installed content from the module, and reset the module using 'dnf module reset <module_name>' command. After you reset the module, you can install the other stream.
すでにPostgreSQL 10のストリームを使っているため怒られました。
RHELのドキュメントにもモジュールに対して有効化できるストリームは1つのみと記載がありました。
あるモジュールの中で同時にアクティブにできるストリームは 1 つだけです。したがって、1 つのシステムにインストールできるコンポーネントは、1 つのバージョンだけです。

Description : PostgreSQL is an advanced Object-Relational database management system (DBMS).
: The base postgresql package contains the client programs that you'll need to
: access a PostgreSQL DBMS server, as well as HTML documentation for the whole
: system. These client programs can be located on the same machine as the
: PostgreSQL server, or on a remote machine that accesses a PostgreSQL server
: over a network connection. The PostgreSQL server can be found in the
: postgresql-server sub-package.

(おまけ) ストリームを指定してインストールする
先ほどはストリームを有効化してからパッケージをインストールしましたが、インストール時に直接ストリームを指定することも可能です。
その場合はdnf module install module-name:streamかdnf install @module-name:streamで行います。
試しにdnf module install postgresql:15を叩いてみましょう。

sudo dnf module install postgresql:15/clientでプロファイルを指定して、PostgreSQLのクライアントをインストールしてみます。

client [i]とクライアントのプロファイルがインストールされたことが分かります。
Application Streamsを使いこなそう
Red Hat Enterprise Linux 8 に PostgreSQL 15 のクライアントをインストールしてみました。
ライフサイクルに注意が必要ですが、Application Streamsを使いこなすことで新しいバージョンのパッケージをインストールすることができます。
新しいバージョンのソフトウェアをインストールしたいがために、ソースからインストールしたり、野性のリポジトリ経由でインストールするということが減りそうですね。
この記事が誰かの助けになれば幸いです。
