This was the error message from an ansible script. I assumed, ansible did the quoting. Doing it per hand, works:
Seems likely that the ansible script is connecting to a different database. Log-rep subscriptions are database-local objects, not cluster-wide, so it matters.
The problem did not happen again after I did a clean clone, where I let CREATE SUBSCRIPTION create the slot.
I implemented this recipe [1] in ansible and it upgraded 2 subscribers and one publisher in 4 minutes from 12 to 13. (-;
