DESTROYUSER(1)                                     DESTROYUSER(1)

       destroyuser  -  Destroy  a  Postgres  user  and associated

       destroyuser [ username ]
       destroyuser [ -h host ] [ -p port ]
           [ username ]

       -h host
              Specifies the hostname of the machine on which  the
              postmaster  is  running.  Defaults to using a local
              Unix domain socket rather than an IP connection.

       -p port
              Specifies the Internet TCP/IP port  or  local  Unix
              domain  socket file extension on which the postmas-
              ter is listening for connections. The  port  number
              defaults  to 5432, or the value of the PGPORT envi-
              ronment variable (if set).

              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.

       destroyuser  will  remove  an  entry  in  the  pg_user  or
       pg_shadow system table, and will remove all databases  for
       which that user is the administrator (DBA).

       Connection to database 'template1' failed.
              destroyuser could not attach to the postmaster pro-
              cess on the specified host and  port.  If  you  see
              this message, ensure that the postmaster is running
              on the proper host and that you have specified  the
              proper  port.  If  your site uses an authentication
              system, ensure that you have obtained the  required
              authentication credentials.

       Connection to database 'template1' failed.
              You  do  not  have  a  valid  entry in the relation
              pg_shadow and and will not  be  allowed  to  access
              Postgres. Contact your Postgres administrator.

       destroyuser: username cannot delete users.
              You do not have permission to delete users; contact
              your Postgres site administrator.

       destroyuser: user "username" already exists
              The user to be added already has an  entry  in  the
              pg_shadow class.

       database access failed
              An  internal error occurred in psql or in the back-
              end server. Ensure that your site administrator has
              properly installed Postgresand initialized the site
              with initdb.

       destroydb on dbname failed - exiting
              An internal error occurred in psql or in the  back-
              end  server.  There was possibly a Unix permissions
              problem with the specified database.

       delete of user username was UNSUCCESSFUL
              An internal error occurred in psql or in the  back-
              end server.

              Note:  destroyuser  internally  runs DROP USER from
              psql while connected to the template1 database.

       destroyuser removes an  existing  Postgres  user  and  the
       databases  for  which that user is database administrator.
       Only users with usesuper set in the  pg_shadow  class  can
       destroy  Postgres users. As shipped, the user postgres can
       remove users.

       destroyuser is a shell script that invokes psql.  Hence, a
       postmaster  process must be running on the database server
       host before destroyuser is  executed.   The  PGOPTION  and
       PGREALM  environment  variables  will be passed on to psql
       and processed as described in psql(1).

       Once  invoked,  destroyuser  will  warn  you   about   the
       databases that will be destroyed in the process and permit
       you to abort the removal of the user if desired.
