dropuser - Drops (removes) a Postgres user
SYNOPSIS
dropuser [ 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.
-i, --interactive
Prompt for confirmation before actually removing
the user.
username
Specifies the name of the Postgres user to be
removed. This name must exist in the Postgres
installation. You will be prompted for a name if
none is 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 they can be confusing in this context.
OUTPUTS
DROP USER
All is well.
dropuser: deletion of user "username" failed
Something went wrong. The user was not removed.
If there is an error condition, the backend error message
will be displayed. See DROP USER [drop_user(l)] and
psql(1) for possibilities.
DESCRIPTION
dropuser removes an existing Postgres user and the
databases which that user owned. Only users with usesuper
dropuser is a shell script wrapper around the SQL command
DROP USER [drop_user(l)] via the Postgres interactive ter
minal psql(1). Thus, there is nothing special about remov
ing 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 remove user joe from the default database server:
$ dropuser joe
DROP USER
To remove user joe using the postmaster on host eden, port
5000, with verification and a peek at the underlying
query:
$ dropuser -p 5000 -h eden -i -e joe
User "joe" and any owned databases will be permanently deleted.
Are you sure? (y/n) y
DROP USER "joe"
DROP USER
