PostgreSQL can't create user [duplicate] - postgresql

Question

This question already has answers here:
In psql, why do some commands have no effect?
(2 answers)
Closed 3 years ago.
Issue: I can create users or databases from the shell (bash, OSX) but not postgres cli. From bash I get no confirmation if successful.
If I try to CREATE ROLE in psql then I get no response and it doesn't generate any error. If I try to createuser from bash then if successful it reports back nothing, if unsuccessful then it does generate the error: "role username already exists".
Example:
Yunti-# CREATE ROLE testuser
Yunti-# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------+-----------
Yunti | Superuser, Create role, Create DB, Replication | {}
anything | | {}
monkey | | {}
Yunti-# CREATE DATABASE testdb
Yunti-# \l
List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges
-----------+-------+----------+-------------+-------------+-------------------
Yunti | Yunti | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
postgres | Yunti | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
template0 | Yunti | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/Yunti +
| | | | | Yunti=CTc/Yunti
template1 | Yunti | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/Yunti +
| | | | | Yunti=CTc/Yunti
test | Yunti | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
test5 | Yunti | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
(6 rows)
Yunti-#
A similar thing happens when using createdb.
How can I create users and databases in postgres cli?
And is this normal to get no response to most postgres commands in bash?
Info: users and their privileges:
Yunti-# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------+-----------
Yunti | Superuser, Create role, Create DB, Replication | {}
anything | | {}
monkey | | {}

Answer 1

Your statements are not executed, because you don't terminate them properly using a ;.
Quote from the manual:
A command is composed of a sequence of tokens, terminated by a semicolon (";").
And in the manual for psql:
At the prompt, the user can type in SQL commands. Ordinarily, input lines are sent to the server when a command-terminating semicolon is reached. An end of line does not terminate a command. Thus commands can be spread over several lines for clarity. If the command was sent and executed without error, the results of the command are displayed on the screen.
If you do that, you get an output like this:
psql (9.4.4)
Type "help" for help.
postgres=# CREATE ROLE testuser;
CREATE ROLE ---<<<< this tells you the statement was executed
postgres=#

I dont know if the postgres client is using other commands in OSX as it is in Linux but I assume it is the same.
This docs link shows some options for the postgres client:
It seems like "\l" lists the databases while the option you would like to see is roles and their access which is "\du".
When creating a database from within the client you should get a response in the form of "CREATING DATABASE". Maybe you are having some sort of syntax error?
I don't think users is created elsewhere.
I hope this solves some of your problems.
