Problemas ao atualizar discourse após algum tempo - FALHA NA ATUALIZAÇÃO DO POSTGRES

Não atualizo o Discourse há algum tempo e tentei fazê-lo hoje. No meu navegador em admin/update, recebo a mensagem de que tudo está atualizado, mas ele está mostrando a versão v2.4.0.beta2 +17 e eu entendo que a versão mais recente é a 3.6.0.beta2.

Então, tentei atualizar via terminal usando ./launcher rebuild app e a atualização falhou, com a mensagem UPGRADE OF POSTGRES FAILED. Li a página de suporte e segui todas as instruções lá e em posts semelhantes sobre problemas de atualização do POSTGRES, mas não consegui resolver o problema.

Eu olhei os logs em /var/discourse/shared/standalone/log/var-log/postgres e encontrei mensagens de erro repetidas, como esta:

2025-11-19 21:42:13.815 GMT [242] LOG: skipping missing configuration file “/shared/postgres_data/postgresql.auto.conf”
2025-11-19 21:42:13.816 UTC [242] FATAL: data directory “/shared/postgres_data” has wrong ownership
2025-11-19 21:42:13.816 UTC [242] HINT: The server must be started by the user that owns the data directory.

Uma coisa que não entendo é que não existe o diretório /shared/postgres_data - mas sim /shared/standalone/postgres_data.

A mensagem de erro do terminal está incluída abaixo. Eu agradeceria qualquer dica para fazer a atualização funcionar.

Obrigado,

Nick


Success. You can now start the database server using:



    /usr/lib/postgresql/13/bin/pg_ctl -D /shared/postgres_data_new -l logfile start
