I have cloned master and in trying to run migrations i get this error:
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation “translation_overrides” does not exist
I see that a topic was created for this last November and seemingly fixed so i’m wondering what coudl be the cause?
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "translation_overrides" does not exist

production but getting it to run on heroku (i realise that heroku is not the ‘supported’, ‘recommended’ setup ). despite that, do you have any ideas? thanks a lot

Isso também ocorre em uma instalação oficial simples do discourse_docker, usando algum teste de restauração automatizado via pipeline todas as manhãs da semana. Esse erro semelhante apareceu repentinamente no pipeline com falha.

A causa raiz foi uma incompatibilidade de versão entre o backup restaurado e o código do contêiner.
O código mais recente do Discourse possui um modelo que referencia a tabela translation_overrides, mas o banco de dados de produção (a partir do backup) está em uma versão anterior em que essa tabela ainda não existe ou tem um nome diferente.
O que funcionou para mim foi reconstruir primeiro (o que cria o esquema do zero) e, em seguida, restaurar o backup. O processo de restauração utiliza a ferramenta de restauração integrada do Discourse, que descarta e recria adequadamente o banco de dados.
). despite that, do you have any ideas? thanks a lot
