CREATEUSER(1) PostgreSQL Client Applications CREATEUSER(1)
NAME
createuser - define a new PostgreSQL user account
SYNOPSIS
createuser [ option... ] [ username ]
DESCRIPTION
createuser creates a new PostgreSQL user (or more precisely, a role). Only superusers and
users with CREATEROLE privilege can create new users, so createuser must be invoked by
someone who can connect as a superuser or a user with CREATEROLE privilege.
If you wish to create a new superuser, you must connect as a superuser, not merely with
CREATEROLE privilege. Being a superuser implies the ability to bypass all access permis-
sion checks within the database, so superuserdom should not be granted lightly.
createuser is a wrapper around the SQL command CREATE ROLE [create_role(7)]. There is no
effective difference between creating users via this utility and via other methods for
accessing the server.
OPTIONS
createuser accepts the following command-line arguments:
username
Specifies the name of the PostgreSQL user to be created. This name must be differ-
ent from all existing roles in this PostgreSQL installation.
-s
--superuser
The new user will be a superuser.
-S
--no-superuser
The new user will not be a superuser. This is the default.
-d
--createdb
The new user will be allowed to create databases.
-D
--no-createdb
The new user will not be allowed to create databases. This is the default.
-r
--createrole
The new user will be allowed to create new roles (that is, this user will have CRE-
ATEROLE privilege).
-R
--no-createrole
The new user will not be allowed to create new roles. This is the default.
-l
--login
The new user will be allowed to log in (that is, the user name can be used as the
initial session user identifier). This is the default.
-L
--no-login
The new user will not be allowed to log in. (A role without login privilege is
still useful as a means of managing database permissions.)
-i
--inherit
The new role will automatically inherit privileges of roles it is a member of.
This is the default.
-I
--no-inherit
The new role will not automatically inherit privileges of roles it is a member of.
-c number
--connection-limit number
Set a maximum number of connections for the new user. The default is to set no
limit.
-P
--pwprompt
If given, createuser will issue a prompt for the password of the new user. This is
not necessary if you do not plan on using password authentication.
-E
--encrypted
Encrypts the user's password stored in the database. If not specified, the default
password behavior is used.
-N
--unencrypted
Does not encrypt the user's password stored in the database. If not specified, the
default password behavior is used.
-e
--echo Echo the commands that createuser generates and sends to the server.
You will be prompted for a name and other missing information if it is not specified on
the command line.
createuser also accepts the following command-line arguments for connection parameters:
-h host
--host host
Specifies the host name of the machine on which the server is running. If the value
begins with a slash, it is used as the directory for the Unix domain socket.
-p port
--port port
Specifies the TCP port or local Unix domain socket file extension on which the
server is listening for connections.
-U username
--username username
User name to connect as (not the user name to create).
-W
--password
Force createuser to prompt for a password (for connecting to the server, not for
the password of the new user).
This option is never essential, since createuser will automatically prompt for a
password if the server demands password authentication. However, createuser will
waste a connection attempt finding out that the server wants a password. In some
cases it is worth typing -W to avoid the extra connection attempt.
ENVIRONMENT
PGHOST
PGPORT
PGUSER Default connection parameters
This utility, like most other PostgreSQL utilities, also uses the environment variables
supported by libpq (see in the documentation).
DIAGNOSTICS
In case of difficulty, see CREATE ROLE [create_role(7)] and psql(1) for discussions of
potential problems and error messages. The database server must be running at the tar-
geted host. Also, any default connection settings and environment variables used by the
libpq front-end library will apply.
EXAMPLES
To create a user joe on the default database server:
$ createuser joe
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n
To create the same user joe using the server on host eden, port 5000, avoiding the prompts
and taking a look at the underlying command:
$ createuser -h eden -p 5000 -S -D -R -e joe
CREATE ROLE joe NOSUPERUSER NOCREATEDB NOCREATEROLE INHERIT LOGIN;
To create the user joe as a superuser, and assign a password immediately:
$ createuser -P -s -e joe
Enter password for new role: xyzzy
Enter it again: xyzzy
CREATE ROLE joe PASSWORD 'md5b5f5ba1a423792b526f799ae4eb3d59e' SUPERUSER CREATEDB CREATEROLE INHERIT LOGIN;
In the above example, the new password isn't actually echoed when typed, but we show what
was typed for clarity. As you see, the password is encrypted before it is sent to the
client. If the option --unencrypted is used, the password will appear in the echoed com-
mand (and possibly also in the server log and elsewhere), so you don't want to use -e in
that case, if anyone else can see your screen.
