Creating manual superuser in cloudsql for postgres

Question

I’m using google managed cloudsql database and I’m trying to create my own superuser manually and I’m getting below message

Note: I’m logged in via existing superuser only(mycurrentuser_dev).

   CREATE ROLE channa WITH LOGIN SUPERUSER PASSWORD 'xxxx';

   SQL Error [42501]: ERROR: must be superuser to create superusers

However, when I checked my current user permission -it has the same permission as cloudsql superuser.

Answer 1

Yeah, cloudsqlsuperuser is not a real superuser. If you want your new role to be as super as it gets, then grant it cloudsqlsuperuser.
