macOSのpostgresqlを更新する
メジャーバージョンアップがあるたびに調べているので次から自分のブログ内で検索を完結できるように書いておく。 今回はbrewで入れたpostgres11から12に更新する作業を行った。
TLDR
brew postgresql-upgrade-database
を叩くと移行が完了する。
ただし古いpostgresが残ってしまうので移行後に brew uninstall postgresql@11
を行っておくほうが良さそう。
補足
雑に brew upgrade
を行ったら11から12に上がってしまい、psqlコマンドが失敗するようになっていたのでどうやって更新するんだったかなぁと調べた。
つまりバージョンを上げてしまった後に上記の移行コマンドを叩いても特に問題はない。
他の記事では上げる前にあれこれする手順も紹介されているが、macOSに関して言うと上げてしまった後に1コマンド叩くだけで移行が完了するのでとても楽だった。
壊れてた時期もあったらしいけど自分が試したときには問題なかった。
