DROPUSER(1) PostgreSQL Client Applications DROPUSER(1)NAMEdropuser - remove a PostgreSQL user account
SYNOPSISdropuser [ options... ] [ username ]
DESCRIPTIONdropuser removes an existing PostgreSQL user and the
databases which that user owned. Only users with usesuper
set in the pg_shadow table can destroy PostgreSQL users.
dropuser is a shell script wrapper around the SQL command
DROP USER [drop_user(l)] via the PostgreSQL interactive
terminal psql(1). Thus, there is nothing special about
removing 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.
OPTIONSdropuser accepts the following command-line arguments:
username
Specifies the name of the PostgreSQL user to be
removed. This name must exist in the PostgreSQL
installation. You will be prompted for a name if
none is specified on the command line.
-e
--echo Echo the queries that dropuser generates and sends
to the server.
-i
--interactive
Prompt for confirmation before actually removing
the user.
-q
--quiet
Do not display a response.
createuser also accepts the following command-line argu-
ments for connection parameters:
-h host
--host host
Specifies the host name of the machine on which the
server is running. If host begins with a slash, it
is used as the directory for the Unix domain
socket.
-p port
--port port
Specifies the Internet TCP/IP port or local Unix
domain socket file extension on which the server is
listening for connections.
-U username
--username username
User name to connect as (not the user name to drop)
-W
--password
Force password prompt (to connect to the server,
not for the password of the user to be dropped).
