.SH NAME
dropuser \- remove a PostgreSQL user account

.SH SYNOPSIS
.sp
\fBdropuser\fR [ \fB\fIoption\fB\fR\fI...\fR ]  [ \fB\fIusername\fB\fR ] 
.SH "DESCRIPTION"
.PP
\fBdropuser\fR removes an existing
PostgreSQL user.
Only superusers and users with the CREATEROLE privilege can
remove PostgreSQL users. (To remove a
superuser, you must yourself be a superuser.)
.PP
\fBdropuser\fR is a wrapper around the
SQL command DROP ROLE [\fBdrop_role\fR(7)].
There is no effective difference between dropping users via
this utility and via other methods for accessing the server.
.SH "OPTIONS"
.PP
\fBdropuser\fR accepts the following command-line arguments:
.TP
\fB\fIusername\fB\fR
Specifies the name of the PostgreSQL user to be removed. 
You will be prompted for a name if none is specified on the command line.
.TP
\fB-e\fR
.TP
\fB--echo\fR
Echo the commands that \fBdropuser\fR generates
and sends to the server.
.TP
\fB-i\fR
.TP
\fB--interactive\fR
Prompt for confirmation before actually removing the user.
.TP
\fB-q\fR
.TP
\fB--quiet\fR
Do not display a response.
.PP
.PP
\fBdropuser\fR also accepts the following
command-line arguments for connection parameters:
.TP
\fB-h \fIhost\fB\fR
.TP
\fB--host \fIhost\fB\fR
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.
.TP
\fB-p \fIport\fB\fR
.TP
\fB--port \fIport\fB\fR
Specifies the TCP port or local Unix domain socket file 
extension on which the server
is listening for connections.
.TP
\fB-U \fIusername\fB\fR
.TP
\fB--username \fIusername\fB\fR
User name to connect as (not the user name to drop)
.TP
\fB-W\fR
.TP
\fB--password\fR
Force password prompt (to connect to the server, not for the
password of the user to be dropped).
.PP
.SH "ENVIRONMENT"
.TP
\fBPGHOST\fR
.TP
\fBPGPORT\fR
.TP
\fBPGUSER\fR
Default connection parameters
.PP
This utility, like most other PostgreSQL utilities,
also uses the environment variables supported by \fBlibpq\fR
(see in the documentation).
.PP
.SH "DIAGNOSTICS"
.PP
In case of difficulty, see DROP ROLE [\fBdrop_role\fR(7)] and \fBpsql\fR(1) 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 \fBlibpq\fR front-end
library will apply.
.SH "EXAMPLES"
.PP
To remove user joe from the default database
server:
.sp
.nf
$ \fBdropuser joe\fR
DROP ROLE
.sp
.fi
.PP
To remove user joe using the server on host
eden, port 5000, with verification and a peek at the underlying
command:
.sp
.nf
$ \fBdropuser -p 5000 -h eden -i -e joe\fR
Role "joe" will be permanently removed.
Are you sure? (y/n) \fBy\fR
DROP ROLE "joe"
DROP ROLE
