Ran this while trying to manage some permissions with Cloud SQL IAM users:
GRANT "****@*****.iam" to postgres;
Now it appears that my postgres account is an IAM user in the DB. And I can't change it back because I can't log in with my original postgres user password. This was also my only superuser account, so I can't get the proper access to change anything back. GCP dashboard also does not let me modify the password because now it's a "System User". Very strange... how do I resolve this?
Tried logging in with the IAM role that I granted to postgres, that does not work... Not sure what to do beyond file a support ticket with GCP
