I have a user `dbadmin`, which has the highest permissions possible in AWS RDS.

Using `dbadmin` I created a database, `foo`, owned by `fooadmin`.

As `fooadmin`, I can `CREATE SCHEMA` in that database. As `dbadmin`, I cannot, I get this error:

    create schema ff;
    ERROR:  permission denied for database foo

My `dbadmin` user certainly has access to this database:

    grant create on database foo to dbadmin;
    WARNING:  no privileges were granted for "foo"
    GRANT

This is sort of the inverse of [this question](https://dba.stackexchange.com/questions/176155/unable-to-create-schema-on-amazon-rds-for-postgres), which was asking how to elevate privileges for `fooadmin`.

**update 1** for EvanC:

    select user;
     current_user
    --------------
     dbadmin
    (1 row)
    
    sdm=> create schema ff;
    ERROR:  permission denied for database foo
