I\'m logged in with a superuser account and this is the process I\'m doing:
1-> CREATE ROLE test WITH IN ROLE testroles PASSWORD \'testpasswd\'
2-> CREATE S
Had this problem with RDS too.
Login as superuser
psql --host=xxxxxxx.rds.amazonaws.com --port=5432 --username=RDS_SUPERUSER_NAME --password --dbname=postgres
Create the User
CREATE USER newuser WITH CREATEDB PASSWORD 'password';
Logout
\q
Login as newuser
psql --host=xxxxxxx.rds.amazonaws.com --port=5432 --username=newuser --password --dbname=postgres
Create your DB/Schema
CREATE SCHEMA/DATABASE ....
