Brian,
you were totally right... I had some runs on trying the upgrade, and that probably caused the DB to be corrupt..
I also noticed that the pg_dump gave me 40 errors when importing..
So: I reinstalled the netbox server totally, and installed a clean 2.9.11 netbox.
Then I took another dump from the original netbox instance (postgres12), but in cleartext, and then imported it into the new netbox instance (postgress11),
That gave me a nice 2.9.11..
then I ran the git based upgrade and all turned out nice !
Sorry to bother you all with my problems, but thank you for your advice !
Pieter
