Resolution

Satellite 6.15 uses postgresql 12. Enable right module and execute satellite-installer to confirm 6.15 is correctly configured:
```
# dnf module disable postgresql:13
# dnf module enable postgresql:12
# satellite-installer
```
Then retry the upgrade to 6.16. The upgrade will modify the postgresql dnf module accordingly to its requirements.
Restore the satellite backup/snapshot on the working state 6.15 and then try to upgrade back to 6.16 latest
