NAME

       dropdb - remove a PostgreSQL database

SYNOPSIS

       dropdb [ option... ]  dbname

DESCRIPTION

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

       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 server.

OPTIONS

       dropdb accepts the following command-line arguments:

       dbname Specifies the name of the database to be removed.

       -e

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

       -i

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

       dropdb 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.

       -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 dropdb to prompt for a password before connecting to a database.

	      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.

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 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.

EXAMPLES

       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;

NAME

       createdb - create a new PostgreSQL database

SYNOPSIS

       createdb [ options... ] [ dbname ] [ description ]

DESCRIPTION

       createdb creates a new PostgreSQL database.

       Normally,  the  database  user who executes this command becomes the owner of the new database.	However a different owner can be specified
       via the -O option, if the executing user has appropriate privileges.

       createdb is a shell script wrapper around the SQL command CREATE DATABASE [create_database(7)]  via  the  PostgreSQL  interactive  terminal
       psql(1).  Thus, there is nothing special about creating databases via this or other methods. This means that the psql program must be found
       by the script and that a database server must be running at the targeted port. Also, any default settings and environment variables  avail-
       able to psql and the libpq front-end library will apply.

OPTIONS

       createdb accepts the following command-line arguments:

       dbname Specifies  the name of the database to be created. The name must be unique among all PostgreSQL databases in this installation.  The
	      default is to create a database with the same name as the current system user.

       description
	      This optionally specifies a comment to be associated with the newly created database.

       -D location

       --location location
	      Specifies the alternative location for the database. See also initlocation(1).

       -e

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

       -E encoding

       --encoding encoding
	      Specifies the character encoding scheme to be used in this database.

       -O owner

       --owner owner
	      Specifies the database user who will own the new database.

       -q

       --quiet
	      Do not display a response.

       -T template

       --template template
	      Specifies the template database from which to build this database.

       The options -D, -E, -O, and -T correspond to options of the underlying SQL command CREATE DATABASE [create_database(7)]; see there for more
       information about them.

       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 the 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

       CREATE DATABASE
	      The database was successfully created.

       createdb: Database creation failed.
	      (Says it all.)

       createdb: Comment creation failed. (Database was created.)
	      The comment/description for the database could not be created.  The database itself will have been created already. You can use  the
	      SQL command COMMENT ON DATABASE to create the comment later on.

       If there is an error condition, the backend error message will be displayed.  See CREATE DATABASE [create_database(7)] and psql(1) for pos-
       sibilities.

ENVIRONMENT

       PGDATABASE
	      If set, the name of the database to create, unless overridden on the command line.

       PGHOST

       PGPORT

       PGUSER Default connection parameters. PGUSER also determines the name of the database to create, if it is not specified on the command line
	      or by PGDATABASE.

EXAMPLES

       To create the database demo using the default database server:

       $ createdb demo
       CREATE DATABASE

       The response is the same as you would have gotten from running the CREATE DATABASE SQL command.

       To create the database demo using the server on host eden, port 5000, using the LATIN1 encoding scheme with a look at the underlying query:

       $ createdb -p 5000 -h eden -E LATIN1 -e demo
       CREATE DATABASE "demo" WITH ENCODING = 'LATIN1'
       CREATE DATABASE
