Upgrade from 12.10.3 to 13.0.0 fails

Hello,

I am running my gitlab with a gitlab-omnibus docker image. when i start the 13.0.0 Omnibus Version on a fresh installation, everything is fine. But when i am trying to upgrade my running 12.10.3 installation to 13.0.0 i run into this error after the container started:

bash[migrate gitlab-rails database] (gitlab::database_migrations line 55) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '1'

timeout: down: postgresql: 1s, normally up, want up

In the logs i see a clear message:

2020-05-26_12:36:39.28723 FATAL:  database files are incompatible with server
2020-05-26_12:36:39.28728 DETAIL:  The data directory was initialized by PostgreSQL version 10, which is not compatible with this version 11.7.

But when i try to run the following, it fails, because the reconfigure fails:

root@776afae8c85a:/# gitlab-ctl pg-upgrade

Then the container dies. Anybody know hot to fix it? If you need anymore informations, just let me know.

Best regards

Update: I found out, that when i setup a new instance, postgresql is installed with 11.7, what makes sense. But when i have a older one with postgresql 9 or 10, upgrade fails.
