Hello,
Just getting back on this and to leave it here for anyone else facing the same issue:
Make sure that no one is working on the same machine at the same time as you. You might also want to check the configuration at the etcd instead of the file, because once the cluster it’s started, it’s there were you need to look.
Ultimately the problem lied at the configuration of patroni, which had a config to always restore to the last possible PITR.
This configuration could be seen with the ‘patronictl edit’, but stupid me, I was looking at the file, because I really thought I was the only one looking at the issue - but clearly that was not the case.
It all ended up making sense after all.
Sorry for the post, thank you for both replies!
