My database is not deploying any more on my prod env

Relevant information to this issue:

ISSUE

Since yesterday at 17:00, the database of our prod environment is facing a deployment error and is stopped. We don’t manage even to connect to it through other tools (like PgAdmin for example).
The other databases of our other environments are not facing this issue.
We didn’t do any action on it yesterday.
What can we test to figure out where is the problem ?
Here are the logs :

Thank you for the help,
