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\&. +.PP +If you wish to create a role with the +SUPERUSER, +REPLICATION, or +BYPASSRLS +privilege, you must connect as a superuser, not merely with +CREATEROLE +privilege\&. Being a superuser implies the ability to bypass all access permission checks within the database, so superuser access should not be granted lightly\&. +CREATEROLE +also conveys +very extensive privileges\&. +.PP +createuser +is a wrapper around the +SQL +command +\fBCREATE ROLE\fR\&. There is no effective difference between creating users via this utility and via other methods for accessing the server\&. +.SH "OPTIONS" +.PP +createuser +accepts the following command\-line arguments: +.PP +\fIusername\fR +.RS 4 +Specifies the name of the +PostgreSQL +user to be created\&. This name must be different from all existing roles in this +PostgreSQL +installation\&. +.RE +.PP +\fB\-c \fR\fB\fInumber\fR\fR +.br +\fB\-\-connection\-limit=\fR\fB\fInumber\fR\fR +.RS 4 +Set a maximum number of connections for the new user\&.

This is the default\&. +.RE +.PP +\fB\-e\fR +.br +\fB\-\-echo\fR +.RS 4 +Echo the commands that +createuser +generates and sends to the server\&. +.RE +.PP +\fB\-E\fR +.br +\fB\-\-encrypted\fR +.RS 4 +This option is obsolete but still accepted for backward compatibility\&. +.RE +.PP +\fB\-g \fR\fB\fIrole\fR\fR +.br +\fB\-\-role=\fR\fB\fIrole\fR\fR +.RS 4 +Indicates role to which this role will be added immediately as a new member\&. Multiple roles to which this role will be added as a member can be specified by writing multiple +\fB\-g\fR +switches\&. +.RE +.PP +\fB\-i\fR +.br +\fB\-\-inherit\fR +.RS 4 +The new role will automatically inherit privileges of roles it is a member of\&. This is the default\&. +.RE +.PP +\fB\-I\fR +.br +\fB\-\-no\-inherit\fR +.RS 4 +The new role will not automatically inherit privileges of roles it is a member of\&. +.RE +.PP +\fB\-\-interactive\fR +.RS 4 +Prompt for the user name if none is specified on the command line, and also prompt for whichever of the options +\fB\-d\fR/\fB\-D\fR, +\fB\-r\fR/\fB\-R\fR, +\fB\-s\fR/\fB\-S\fR +is not specified on the command line\&. (This was the default behavior up to PostgreSQL 9\&.1\&.) +.RE +.PP +\fB\-l\fR +.br +\fB\-\-login\fR +.RS 4 +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\&. +.RE +.PP +\fB\-L\fR +.br +\fB\-\-no\-login\fR +.RS 4 +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\&.) +.RE +.PP +\fB\-P\fR +.br +\fB\-\-pwprompt\fR +.RS 4 +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\&. +.RE +.PP +\fB\-r\fR +.br +\fB\-\-createrole\fR +.RS 4 +The new user will be allowed to create, alter, drop, comment on, change the security label for, and grant or revoke membership in other roles; that is, this user will have +CREATEROLE +privilege\&. See +role creation +for more details about what capabilities are conferred by this privilege\&. +.RE +.PP +\fB\-R\fR +.br +\fB\-\-no\-createrole\fR +.RS 4 +The new user will not be allowed to create new roles\&.

If the server requires password authentication and a password is not available by other means such as a +\&.pgpass +file, the connection attempt will fail\&. This option can be useful in batch jobs and scripts where no user is present to enter a password\&. +.RE +.PP +\fB\-W\fR +.br +\fB\-\-password\fR +.RS 4 +Force +createuser +to prompt for a password (for connecting to the server, not for the password of the new user)\&. +.sp +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 +\fB\-W\fR +to avoid the extra connection attempt\&. +.RE +.SH "ENVIRONMENT" +.PP +\fBPGHOST\fR +.br +\fBPGPORT\fR +.br +\fBPGUSER\fR +.RS 4 +Default connection parameters +.RE +.PP +\fBPG_COLOR\fR +.RS 4 +Specifies whether to use color in diagnostic messages\&.
