Cloud SQL Postgress - current user cannot be dropped after database maintenance

[davidgarcia]

After an automatic maintenance today, our Cloud SQL Postgress 15.7 database is throwing an error in logs every 15 minutes.

This is the sequence that triggers the error:

db=cloudsqladmin,user=cloudsqladmin LOG: statement: DROP ROLE "cloudsqladmin"

db=cloudsqladmin,user=cloudsqladmin ERROR: current user cannot be dropped

Any clue what might be happening? The statement is not executed by any application but internally by Google Cloud.

Thanks!

I'm encountering the same issue but in a pgsql 16.3 version instance. Did you find a cause or solution?
