Estou tentando atualizar minha instância do Discourse de 2.9.0.beta10 para 3.2.0.beta1.  
Estou recebendo um erro como este:

FAILED
--------------------
Pups::ExecError: cd /var/www/discourse &amp;&amp; su discourse -c 'bundle exec rake db:migrate' failed with return #<Process::Status: pid 787 exit 1>

```

## Alguma ideia do que está errado? Eu já atualizei minha instância anteriormente sem erros. O Discourse Doctor não me deu nenhuma pista para procurar.

A mensagem acima se refere a esta instrução SQL?

```sql
UPDATE tags t
SET public_topic_count = x.topic_count
FROM (
	SELECT COUNT(topics.id) AS topic_count,    
	tags.id AS tag_id
	FROM tags
	INNER JOIN topic_tags ON tags.id = topic_tags.tag_id
	INNER JOIN topics ON topics.id = topic_tags.topic_id AND topics.deleted_at IS NULL AND topics.archetype != 'private_message'
	INNER JOIN categories ON categories.id = topics.category_id AND NOT categories.read_restricted
	GROUP BY tags.id
) x
	WHERE x.tag_id = t.id
	AND x.topic_count <> t.public_topic_count;

```

Porque se eu executar apenas o código `SELECT` no banco de dados diretamente, não recebo erros.  
Vejo que o trabalho `db:migrate` primeiro adiciona a coluna com  
` add_column(:tags, :public_topic_count, :integer, {:default=>0, :null=>false})`  
Não sei por que falha na consulta acima então?
