       dropdb - remove a PostgreSQL database


       dropdb [ option... ]  dbname


       dropdb destroys an existing PostgreSQL database.  The user who executes
       this command must be a database superuser or the owner of the database.

       dropdb   is   a   wrapper   around   the   SQL  command  DROP  DATABASE
       [drop_database(7)].  There is no effective difference between  dropping
       databases  via  this  utility  and  via other methods for accessing the


       dropdb accepts the following command-line arguments:

       dbname Specifies the name of the database to be removed.


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


              Issues  a verification prompt before doing anything destructive.

       dropdb also accepts the following command-line arguments for connection

       -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.


              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.


              Force dropdb to prompt for a password  before  connecting  to  a

              This  option is never essential, since dropdb will automatically
              prompt  for  a  password  if   the   server   demands   password
              authentication.  However, dropdb 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.




       PGUSER Default connection parameters

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


       In case of difficulty, see DROP DATABASE [drop_database(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.


       To destroy the database demo on the default database server:

       $ dropdb demo

       To destroy the database demo using the server on host eden, port  5000,
       with verification and a peek at the underlying command:

       $ dropdb -p 5000 -h eden -i -e demo
       Database "demo" will be permanently deleted.
       Are you sure? (y/n) y
       DROP DATABASE demo;
