DROPDB(1)


NAME

  dropdb - remove a PostgreSQL database


SYNOPSIS

  dropdb [ options... ] dbname


DESCRIPTION

  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 shell script wrapper around the SQL command DROP DATABASE
  [drop_database(5)] via the PostgreSQL interactive terminal psql(1). Thus,
  there is nothing special about dropping databases 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.


OPTIONS

  dropdb accepts the following command-line arguments:

  dbname
       Specifies the name of the database to be removed. The database must be
       one of the existing PostgreSQL databases in this installation.

  -e

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

  -i

  --interactive
       Issues a verification prompt before doing anything destructive.

  -q

  --quiet
       Do not display a response.

  createdb 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 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

  -W

  --password
       Force password prompt.


DIAGNOSTICS

  DROP DATABASE
       The database was successfully removed.

  dropdb: Database removal failed.
       Something didn't work out.

  If there is an error condition, the backend error message will be
  displayed.  See DROP DATABASE [drop_database(5)] and psql(1) for
  possibilities.


ENVIRONMENT

  PGHOST

  PGPORT

  PGUSER
       Default connection parameters


EXAMPLES

  To destroy the database demo on the default database server:

  $ dropdb demo
  DROP DATABASE

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

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