PostgreSQL: role is not permitted to log in

Using pgadmin4 :

1. Select roles in side menu
2. Select properties in dashboard.
3. Click Edit and select privileges

Now there you can enable or disable login, roles and other options

CREATE ROLE blog WITH
  LOGIN
  SUPERUSER
  INHERIT
  CREATEDB
  CREATEROLE
  REPLICATION;

COMMENT ON ROLE blog IS 'Test';

The role you have created is not allowed to log in. You have to give the role permission to log in.

One way to do this is to log in as the postgres user and update the role:

psql -U postgres

Once you are logged in, type:

ALTER ROLE "asunotest" WITH LOGIN;

Here's the documentation http://www.postgresql.org/docs/9.0/static/sql-alterrole.html
