createuserNamecreateuser -- define a new EnterpriseDB user account Synopsiscreateuser [option...] [username] Description createuser creates a
new EnterpriseDB user.
Only superusers (users with usesuper set in
the pg_shadow table) can create
new EnterpriseDB users,
so createuser must be
invoked by someone who can connect as a EnterpriseDB
superuser.
Being a superuser also implies the ability to bypass access permission
checks within the database, so superuser status should not be granted lightly.
createuser is a wrapper around the
SQL command CREATE USER.
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 EnterpriseDB user to be created.
This name must be unique among all EnterpriseDB users.
- -a
--adduser The new user is allowed to create other users.
(Note: Actually, this makes the new user a superuser.
The option is poorly named.)
- -A
--no-adduser The new user is not allowed to create other users (i.e.,
the new user is a regular user, not a superuser).
This is the default.
- -d
--createdb The new user is allowed to create databases.
- -D
--no-createdb The new user is not allowed to create databases.
This is the default.
- -e
--echo Echo the commands that createuser generates
and sends to the server.
- -E
--encrypted Encrypts the user's password stored in the database. If not
specified, the default password behavior is used.
- -i number
--sysid number Allows you to pick a non-default user ID for the new user. This is not
necessary, but some people like it.
- -N
--unencrypted Does not encrypt the user's password stored in the database. If
not specified, the default password behavior is used.
- -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.
- -q
--quiet Do not display a response.
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 password prompt (to connect to the server, not for the
password of the new user).
Environment- PGHOST
PGPORT
PGUSER Default connection parameters
Diagnostics In case of difficulty, see CREATE USER and edb-psql for
discussions of potential problems and error messages.
The database server must be running at the
targeted 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
Is the new user allowed to create databases? (y/n) n
Shall the new user be allowed to create more new users? (y/n) n
CREATE USER
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 -p 5000 -h eden -D -A -e joe
CREATE USER "joe" NOCREATEDB NOCREATEUSER
CREATE USER
