NAME

       dropuser - remove a PostgreSQL user account

SYNOPSIS

       dropuser [ option... ]  [ username ]

DESCRIPTION

       dropuser  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.)

       dropuser  is  a  wrapper  around  the  SQL  command DROP ROLE [drop_role(7)].  There is no
       effective difference between dropping users via this utility and  via  other  methods  for
       accessing the server.

OPTIONS

       dropuser accepts the following command-line arguments:

       username
              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.

       -e

       --echo Echo the commands that dropuser generates and sends to the server.

       -i

       --interactive
              Prompt for confirmation before actually removing the user.

       dropuser also accepts the following command-line arguments for connection parameters:

       -h host

       --host host
              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.

       -p port

       --port port
              Specifies  the  TCP  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

       --no-password
              Never issue a password prompt. If the server requires password authentication and a
              password  is  not  available  by other means such as a .pgpass file, the connection
              attempt will fail. This option can be useful in batch jobs  and  scripts  where  no
              user is present to enter a password.

       -W

       --password
              Force dropuser to prompt for a password before connecting to a database.

              This  option  is  never  essential,  since dropuser will automatically prompt for a
              password if the server demands password  authentication.   However,  dropuser  will
              waste  a  connection attempt finding out that the server wants a password.  In some
              cases it is worth typing -W to avoid the extra connection attempt.

ENVIRONMENT

       PGHOST

       PGPORT

       PGUSER Default connection parameters

       This utility, like most other PostgreSQL utilities, also uses  the  environment  variables
       supported by libpq (see in the documentation).

DIAGNOSTICS

       In  case  of  difficulty,  see  DROP  ROLE  [drop_role(7)]  and psql(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
       libpq front-end library will apply.

EXAMPLES

       To remove user joe from the default database server:

       $ dropuser joe

       To remove user joe using the server on host eden, port 5000, with verification and a  peek
       at the underlying command:

       $ dropuser -p 5000 -h eden -i -e joe
       Role "joe" will be permanently removed.
       Are you sure? (y/n) y
       DROP ROLE joe;
