NAME

createuser - Create a new Postgres user

SYNOPSIS

createuser [ options... ] [ username ] INPUTS -h, --host host Specifies the hostname of the machine on which the postmaster is running. If host begins with a slash, it is used as the directory for the unix domain socket. -p, --port port Specifies the Internet TCP/IP port or local Unix domain socket file extension on which the postmas­ ter is listening for connections. -e, --echo Echo the queries that createdb generates and sends to the backend. -q, --quiet Do not display a response. -d, --createdb Allows the new user to create databases. -D, --no-createdb Forbids the new user to create databases. -a, --adduser Allows the new user to create other users. -A, --no-adduser Forbids the new user to create other users. -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. -i, --sysid uid Allows you to pick a non-default user id for the new user. This is not necessary, but some people like it. username Specifies the name of the Postgres user to be cre­ ated. This name must be unique among all Postgres users. You will be prompted for a name and other missing informa­ tion if it is not specified on the command line. The options -h, -p, and -e, are passed on literally to psql(1). The psql options -U and -W are available as well, but their use can be confusing in this context. OUTPUTS CREATE USER All is well. createuser: creation of user "username" failed Something went wrong. The user was not created. If there is an error condition, the backend error message will be displayed. See CREATE USER [create_user(l)] and psql(1) for possibilities.

DESCRIPTION

createuser creates a new Postgres user. Only users with usesuper set in the pg_shadow table can create new Post­ gres users. createuser is a shell script wrapper around the SQL com­ mand CREATE USER [create_user(l)] via the Postgres inter­ active terminal psql(1). Thus, there is nothing special about creating users via this or other methods. This means that the psql must be found by the script and that a database server is running at the targeted host. Also, any default settings and environment variables available to psql and the libpq front-end library do apply. USAGE 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 postmaster on host eden, port 5000, avoiding the prompts and taking a look at the underlying query: $ createuser -p 5000 -h eden -D -A -e joe CREATE USER "joe" NOCREATEDB NOCREATEUSER CREATE USER Application 2000-11-11 CREATEUSER(1)
