.SH DESCRIPTION
|
|
.IR Createuser
|
|
creates a new Postgres user. Only users with \*(lqusesuper\*(rq set in
|
|
the \*(lqpg_user\*(rq class can create new Postgres users. As shipped,
|
|
the user \*(lqpostgres\*(rq can create users.
|
|
.PP
|
|
.IR Createuser
|
|
is a shell script that invokes
|
|
.IR psql .
|
|
Hence, a
|
|
.IR postmaster
|
|
process must be running on the database server host before
|
|
.IR createuser
|
|
is executed. In addition, the
|
|
.SM PGOPTION
|
|
and
|
|
.SM PGREALM
|
|
environment
|
|
variables will be passed on to
|
|
.IR psql
|
|
and processed as described in
|
|
.IR psql (1).
|
|
.PP
|
|
The optional argument
|
|
.IR username
|
|
specifies the name of the Postgres user to be created. (The invoker will
|
|
be prompted for a name if none is specified on the command line.)
|
|
This name must be unique among all Postgres users.
|
|
.PP
|
|
.IR Createuser
|
|
understands the following command-line options:
|
|
.TP 5n
|
|
.BR "-a" " system"
|
|
Specifies an authentication system
|
|
.IR "system"
|
|
(see
|
|
.IR introduction (1))
|
|
to use in connecting to the
|
|
.IR postmaster
|
|
process. The default is site-specific.
|
|
.TP
|
|
.BR "-h" " host"
|
|
Specifies the hostname of the machine on which the
|
|
.IR postmaster
|
|
is running. Defaults to the name of the local host, or the value of
|
|
the
|
|
.SM PGHOST
|
|
environment variable (if set).
|
|
.TP
|
|
.BR "-p" " port"
|
|
Specifies the Internet TCP port on which the
|
|
.IR postmaster
|
|
is listening for connections. Defaults to 5432, or the value of the
|
|
.SM PGPORT
|
|
environment variable (if set).
|
|
.SH "INTERACTIVE QUESTIONS"
|
|
Once invoked with the above options,
|
|
.IR createuser
|
|
will ask a series of questions. The new users's login name (if not
|
|
given on the command line) and user-id must be specified. (Note that
|
|
the Postgres user-id must be the same as the user's Unix user-id.) In
|
|
addition, you must describe the security capabilities of the new user.
|
|
Specifically, you will be asked whether the new user should be able to
|
|
act as Postgres super-user, create new databases and update the system
|
|
catalogs manually.

.SH DIAGNOSTICS
|
|
.TP 5n
|
|
.BI "Error: Failed to connect to backend (host=" "xxx" ", port=" "xxx" ")"
|
|
.IR Createuser
|
|
could not attach to the
|
|
.IR postmaster
|
|
process on the specified host and port. If you see this message,
|
|
ensure that the
|
|
.IR postmaster
|
|
is running on the proper host and that you have specified the proper
|
|
port. If your site uses an authentication system, ensure that you
|
|
have obtained the required authentication credentials.
|
|
.TP
|
|
.BI "user \*(lq" "username" "\*(rq is not in \*(lqpg_user\*(rq"
|
|
You do not have a valid entry in the relation \*(lqpg_user\*(rq and
|
|
cannot do anything with Postgres at all; contact your Postgres site
|
|
administrator.
|
|
.TP
|
|
.IB "username" " cannot create users."
|
|
You do not have permission to create new users; contact your Postgres
|
|
site administrator.
|
|
.TP
|
|
.BI "user \*(lq" "username" "\*(rq already exists"
|
|
The user to be added already has an entry in the \*(lqpg_user\*(rq
|
|
class.
|
|
.TP
|
|
.BR "database access failed"
|
|
An internal error occurred in
|
|
.IR psql
|
|
or the backend server. Ensure that your Postgres site administrator has
|
|
properly installed Postgres and initialized the site with
|
|
.IR initdb .
|
|
.SH BUGS
|
|
Postgres user-ids and user names should not have anything to do with the
|
|
constraints of Unix.
