Hey there.

Is this the version of SonarQube you’re trying to use? It is very, very outdated if so.

I would suggest reverting your installation to v11.19, updating your SonarQube instance to a supported version (v9.9 or v10.3) (all versions still support Postgres 11) and then start workign through your Postgres upgrade.
