Sonarqube data erased at startup

Thanks for your answer.
yes, everything looked normal after we upgraded and the only modifications we made to the database was to regrant our admin user admin right (because i accidentally deleted admin group) : Deleted sonar-admins group by mistake

The values are “sonar.jdbc.url”:“jdbc:postgresql://sonarqube-postgresql:5432/sonarDB”
and “sonar.jdbc.username”:“sonarUser”
Do you think it should be fine ? We haven’t touched anything for it.
But, when I go to the postgresql-sonarqube pod and try to log on psql with this user and the password registered on the secret, it doesn’t works. Is it possible there is a bug in the chart with this version with postgresql ?
But in that case, is it normal sonar can still start ? Without connection to the database, shouldn’t it block at startup ?
