 Looking at /var/log/gitea/gitea.log we seem to have some out-of-date
 database structure.

 Examples:
 ```
 2023/08/29 06:12:10 cmd/web.go:175:serveInstalled() [W] Table webhook
 Column is_system_webhook db nullable is false, struct nullable is true
 2023/08/29 06:12:10 cmd/web.go:175:serveInstalled() [W] Table hook_task
 column id db type is SERIAL, struct type is BIGSERIAL
 2023/08/29 06:12:10 cmd/web.go:175:serveInstalled() [W] Table hook_task
 has column repo_id but struct has not related field
 2023/08/29 06:12:10 cmd/web.go:175:serveInstalled() [W] Table review
 column type db type is VARCHAR(255), struct type is INTEGER
 ```

 There might be a missing upgrade procedure step to be performed (maybe on
 staging first)
