The doc GitLab 12 specific changes | GitLab states “PostgreSQL will automatically be upgraded to 10.x unless specifically opted out during the upgrade. To opt out you must execute the following before performing the upgrade of GitLab.”
I just carried out a single node zero downtime upgrade from v11.11 to v12.0.12 per Update GitLab installed with the Omnibus GitLab package | GitLab but when I run the Gitlab rails console, the PostgreSQL version reads as follows -
[root@mygitlabserver myuser]# gitlab-rails console
GitLab: 12.0.12 (ce125b970e4)
GitLab Shell: 9.3.0
Please can you advise what version PostgreSQL should be at and if mine is down-rev, how this has happened and how I should address this at this point?
I believe I stuck to the upgrade process and I see v12.0.12 RPM installed (CentOS 7) and the GUI/help screen says 12.0.12.
I could provide my upgrade process somewhere if that would help but it contains the official Gitlab process above plus some local steps for backups, etc.
