colonne ID_requête manquant dans pg_stat_statements tableau

Question

Nous avons une base de données postgres Heroku qui exécute la version 9.6.1

Lors de la mise à niveau de notre installation pghero à la nouvelle version 2.0.2, nous obtenons des échecs que pghero n'est pas en mesure pour trouver la colonne queryid dans la table pg_stat_statements. L'extension pg_stat_statements est installée.

Answer 1

Il se avère que la mise à niveau de la version postgres sur Heroku ne met pas à jour les extensions nécessairement à la version la plus récente.

Mise à jour de l'extension en exécutant

ALTER EXTENSION pg_stat_statements UPDATE; 

résolu le problème.
