What is your database version ?

Solved: in this particular installation I never logged in,so the upgrade script never executed. Thank you to address me to right direction!

How do you update ?
If you update via CLI : https://github.com/LimeSurvey/LimeSurvey/blob/master/application/commands/UpdateDbCommand.php

Else : we must avoid such situation i think.
I look at a potential solution

No, i let the upgrade runs during the first login as admin.
I think it is a reasonable behavior: the admin must check everything is working after upgrade.
But we have 5 installations in production, sometimes I forget to check them. My mistake.

There are potential solution, if we can avoid public issue it's better :)

As per the comments, will be closing the ticket.
Please add any comments in case it should be reopened.
Thanks
