Postgres cannot create database but can create a user
I am using Ubuntu Linux. I am trying to use Postgres as database. It is doing fine when I created a user:
CREATE USER username;
But when I try to create a database, it returns nothing:
CREATE DATABASE databasename;
What is happening with my Postgres?
